The Safest Way to Relight a Pilot Light in Your Older Hollins Market Home
When your furnace suddenly stops producing heat on a freezing Baltimore night, a failed pilot light is often the culprit. For homeowners in Hollins Market with older gas furnaces, boilers, or floor heaters, knowing how to safely relight that pilot can restore warmth without an emergency service call. This guide walks you through the exact process for Baltimore’s historic housing stock, complete with safety warnings specific to our aging gas infrastructure and local building codes. Baltimore Gas and Electric Safety Information.
- Turn Off the Gas Supply
Locate the main gas valve near your furnace and turn it to the “off” position. This allows any accumulated gas to dissipate safely. Wait at least 5 minutes before proceeding.
- Locate the Pilot Assembly
Remove the front panel of your furnace to access the pilot light assembly. In older Hollins Market homes, this is often near the bottom of the unit, sometimes requiring a flashlight to see clearly.
- Switch to Pilot Mode
Turn the gas control knob to the “pilot” position. This prepares the system to receive the flame without flooding the chamber with gas.
- Ignite the Pilot
Press and hold the reset button while using a long-reach lighter to ignite the pilot flame. Continue holding for 30-60 seconds to allow the thermocouple to heat up.
- Release and Verify
Slowly release the reset button. If the pilot stays lit, turn the gas valve to “on” and replace the furnace cover. If it goes out, repeat the process or check for obstructions.
Safety First: When to Stop and Call a Professional
Never attempt to relight a pilot if you smell gas anywhere in your home. This distinct rotten egg odor indicates a potential gas leak that requires immediate evacuation and emergency response. Baltimore Gas and Electric (BGE) operates a 24/7 emergency line at 1-800-642-3029 for gas leak reports. Leave your Hollins Market home immediately and call from a safe location.

Other warning signs that require professional service include a yellow or flickering pilot flame (indicating incomplete combustion), soot buildup around the unit, or if the pilot won’t stay lit after multiple attempts. These symptoms often point to a failing thermocouple, clogged pilot orifice, or even a cracked heat exchanger—all serious safety hazards that violate Baltimore City mechanical codes.

- Carbon monoxide detector (test before starting)
Understanding Your Hollins Market Furnace
Many homes in the Hollins Market historic district were built between 1880 and 1940, featuring gravity furnaces or early forced-air systems with standing pilot lights. These units often have pilot assemblies that differ from modern designs. The pilot orifice in these older systems tends to accumulate carbon deposits more quickly due to Baltimore’s humid climate and the age of the gas lines feeding them. Carbon Monoxide Leak Detection.
Unlike newer electronic ignition systems, standing pilot lights burn continuously, consuming about 5-10 therms of gas monthly. This constant operation means the thermocouple—a safety device that detects whether the pilot is lit—wears out more frequently in older units. A failing thermocouple is the most common reason a pilot won’t stay lit after ignition.
Troubleshooting Common Pilot Light Problems
If your pilot lights but won’t stay lit, the thermocouple likely needs cleaning or replacement. Use fine sandpaper to gently clean the thermocouple tip, removing any oxidation that prevents proper heat detection. If cleaning doesn’t work, the part needs replacement—a simple fix for any Baltimore HVAC technician familiar with historic home systems.
A pilot that lights but produces a weak, yellow flame indicates a clogged orifice. Baltimore’s aging gas infrastructure can send debris through the lines, especially after nearby construction or utility work. Use a needle to carefully clear the tiny opening, but never enlarge it, as this affects combustion efficiency and safety.
Drafts from old windows or poorly sealed crawl spaces in Hollins Market homes can blow out pilot lights. Check for drafts by holding a lit incense stick near the furnace during ignition. If the smoke wavers, you’ve found the source of your problem. Weatherstripping or temporary draft blockers can solve this issue.
Baltimore-Specific Safety Considerations
Hollins Market sits on land with heavy clay soil that expands and contracts with moisture changes. This movement can stress gas line connections over decades, potentially creating micro-leaks that are difficult to detect. Always use a gas leak detector spray on connections after any maintenance work. Bubbles indicate a leak requiring immediate professional attention.
Baltimore City Code Article 15, Title 4 requires permits for any work involving gas line modifications. While relighting a pilot doesn’t require a permit, any replacement of gas valves, thermocouples, or related components does. Always hire a licensed HVAC contractor familiar with Baltimore’s specific mechanical permit requirements.
Maryland’s high humidity levels mean older furnaces in Hollins Market homes are more susceptible to corrosion. Check the heat exchanger annually for rust or cracks, which can allow carbon monoxide to enter your living space. Install carbon monoxide detectors on every level of your home, particularly near sleeping areas. Maryland State Government Resources.
When to Replace vs. Repair
Standing pilot furnaces over 25 years old typically operate at 60-70% efficiency compared to modern 95% efficient units. For Hollins Market homeowners, the decision to repair or replace often comes down to the unit’s age and your long-term plans. If your furnace is original to the home and over 40 years old, replacement with a high-efficiency model may be more cost-effective.
Modern high-efficiency furnaces eliminate the standing pilot entirely, using electronic ignition that only activates when heat is needed. This saves approximately 10-15 therms of gas monthly during heating season. Many Hollins Market homeowners choose this upgrade when renovating, as it eliminates the maintenance headaches of aging pilot systems.
However, if your historic home has radiator heating rather than forced air, you likely have a boiler system. These systems use pilot lights differently and require specialized knowledge of steam or hot water heating common in Baltimore’s older housing stock.
Preventing Future Pilot Light Problems
Annual maintenance by a qualified Baltimore HVAC technician can prevent most pilot light failures. During a tune-up, the technician will clean the pilot assembly, test the thermocouple, check gas pressure, and inspect the heat exchanger for cracks. This service typically costs $150-250 but can prevent emergency calls during winter storms.
Change your furnace filter monthly during heating season. A clogged filter restricts airflow, causing the furnace to work harder and potentially affecting pilot operation. Use pleated filters rated MERV 8-11 for the best balance of filtration and airflow in older systems.
Consider installing a programmable thermostat if you don’t have one. These devices reduce furnace cycling, extending the life of all components including the pilot system. Smart thermostats can also alert you to system problems before you notice a lack of heat.
Local Resources and Emergency Contacts
For Hollins Market residents, several local resources can help with heating emergencies. The Baltimore City Department of Housing and Community Development offers emergency heating assistance for income-qualified residents. Contact them at (443) 984-1809 during business hours.
Several local HVAC companies specialize in historic Baltimore home systems. Look for contractors with experience in rowhome heating systems and familiarity with Baltimore Gas and Electric’s specific requirements for gas appliances in the city.
If you’re renting in Hollins Market, your lease likely requires the landlord to maintain heating systems. Document any maintenance requests in writing and know your rights under Baltimore City’s landlord-tenant laws, which require functional heating from October through April.
Frequently Asked Questions
How do I know if my pilot light is out?
If your furnace isn’t producing heat and you don’t hear the burner igniting, check the small window or opening near the bottom of the unit. If you see no flame, your pilot light is out. Some units have a viewing port specifically for this purpose.
How long should I hold the reset button when relighting?
Hold the reset button for 30-60 seconds after the pilot lights. This allows the thermocouple to reach operating temperature. If you release too soon, the safety system will shut off the gas, thinking the pilot failed to ignite.
Can I use a regular lighter to relight the pilot?
No. Always use a long-reach lighter designed for fireplaces or grills. Regular lighters place your hand too close to the gas port, creating a burn hazard. The extended reach also helps you see the pilot while igniting it.
