TAKING CARE
OF YOUR BOILER
At least once each month during the heating season, perform the following inspections:
Check Vent Tubing: Look for leakage at joints and sagging of vent tubing runs. If evident, call a qualified service technician.
Check Vent Terminal (Outside): Look for and remove any obstructions (i.e. leaves, shrubs, snow).
Check Water Piping: Look for leaks around boiler and at all joints. If evident, call a qualified service technician.
Check System Water Pressure: The temperature/pres- sure gage indicates the pressure in the boiler for each water temperature. For most installations, it should indicate about 12 psi to 15 psi for 70° to 100° water temperatures and from 15 psi to 25 psi for temperatures up to 240°. Ask your installer or service technician to explain and show you what normal pressures to look for.
If pressure decreases from normal, the system is losing water; if pressure increases from normal, the boiler relief valve will open to relieve pressure (water will be evident on floor below relief valve discharge piping). In either case, call a qualified service technician.
At least once a year, check the air filter: Replace it (recommended) or clean it. For access to the filter, remove boiler front cover by pushing down on top center portion of cover until support clip releases cover at top, then lift off of support clips at bottom of cover.
Open air filter box cover by rotating the 1/4 turn fastener on top of cover, then swing open at hinge.
