Operating instructions

MAINTENANCE
To assure trouble-free operation, we recommend that flue passages, burner, combustion chamber area (target wall and fire door insulation), burner
adjustment, operation of controls, and boiler seals (door gasket or silicone seal, cast iron seals and flue collector) be checked ONCE EACH YEAR
by a competent service technician.
BEFORE THE START OF EACH SEASON (or whenever system has been shut down for some time), recheck the whole system for leaks and
recheck boiler and vent pipe for leaks. Replace or patch any boiler seals that are faulty.
WARNING: Never burn garbage or paper in the unit, and never leave combustible material around it.
PROCEDURE 1—RELIEF VALVE
This valve should open automatically when system pressure exceeds the safe limit (30 psi). Should it ever fail to open under this condition, shut
system down. Drain it until pressure is reduced below safe limit, then have valve replaced immediately. The relief valve should be tested monthly
during heating season. Prior to testing, make certain a discharge pipe is properly connected to the valve outlet and arranged so as to contain and
safely dispose of boiler discharge. Hold the trip lever fully open for at least five seconds in order to flush free any sediment that may lodge on
the valve seat. Then permit the valve to snap shut.
PROCEDURE 2—CONVENTIONAL EXPANSION TANK
As previously noted, this tank may become waterlogged or may receive an excess of air. Frequent automatic opening of relief valve indicates
waterlogging. A high boiler temperature accompanied by unusually low radiation unit temperature (and ″knocking″) indicates excess air in tank.
