MAINTENANCE CLEANING
Annual service and maintenance (preferably at the beginning of each heating season)
by a qualified service agency must be performed to assure continued safe trouble-free
operation and maximum efficiency. The boiler owner SHOULD NOT attempt these
procedures. This annual service should include, at a minimum: examining the flue
passages between boiler sections, burner, and condensate lines, and cleaning if
necessary; inspecting venting and air intake system and cleaning if necessary; placing
the boiler in operation and performing the checkout procedure; inspecting the
condensate drain pipe and cleaning if necessary; and checking all gasketed and
threaded joints for leakage and repairing if necessary. Particular attention should be
given to potential deterioration from corrosion or other sources. Detailed procedures for
maintenance and cleaning can be found in the Modulex Installation, Operation and
Maintenance Manual GF-115.
The boiler owner should perform the following periodic maintenance procedures.
A. Daily during heating season:
Check that the boiler area is free from combustible materials, gasoline and other
flammable vapors and liquids.
Check for, and remove, any obstruction to the flow of combustion air or venting of
flue gases.
B. Monthly during heating season:
Remove front and top jacket panels and check for piping leaks around relief valve
and other fittings. If found, contact a qualified service agency to repair.
DO NOT use stop leak compounds.
Test relief valve. Refer to relief valve manufacturer’s instructions packaged with
relief valve.
Visually inspect the venting and air intake system for proper function, deterioration,
or leakage. If the vent or air intake show any signs of deterioration or leakage,
contact a qualified service agency to repair or replace them immediately and to
insure proper reassembly and resealing of the vent and air intake system.
Visually inspect the condensate line and the PVC drainpipe for proper operation,
leakage, and deterioration. If the condensate line or drain pipe show any signs of
blockage, leakage, or deterioration, contact a qualified service agency to clean,
repair, or replace them immediately.
Check air vent(s) for leakage.
