2.Condensation drain trap inspection

Check condensation drain trap to be full of water. Check for deterioration of the tubing. Check that trap is not plugged. DO NOT operate the boiler without filling the trap with water to prevent flue gas discharge into space. The drain should extend to a floor drain or to a contain- er which may require emptying periodically.

3.Piping inspection

Look at all water piping. There should be no leaks or signs of leaks at any pipe joints or around the boiler.

4.System water pressure inspection

The temperature and pressure gauge indicates the pressure in the boiler at each water temperature. For most installations, it should indicate about 12 to 15 psi pressure when temperature is about 70 to 100° F and from 15 psi to 25 psi when temperature is up to 240° F. FOR YOUR SYSTEM, there is one correct pressure for each temperature. ASK YOUR INSTALLER OR SERVI- CEPERSON TO EXPLAIN AND SHOW YOU. Learn what normal pressures to look for. If pressure decreas- es from normal, your system is losing water. If pressure rises from normal, the relief valve will open to relieve the pressure. Call your service organization if pressures are higher or lower than normal, and if the relief valve spills water. Repair or adjustment is needed.

5.Unusual noise

Stand near the boiler and look and listen. As the burn- ers start and shut off, there should be no unusual noise. No fire should be visible coming out from the front of the boiler when the burners start or run.

6.Boiler room air supply inspection

Ample air is required for your boiler to burn fuel cleanly and safely. Check to make sure all air vents are open and free of obstruction. Air needs are greatest in cold weather.

WARNING: The flow of combustion and ventilating air to the boiler should not be obstructed.

WARNING: If you find any problem during your inspection, call for service immediately.

A trained and qualified service technician should per- form these inspections before each heating season:

1.Safety check
