14.6 Preventive Maintenance
-
Inspect boiler and vent pipe for accumulation of soot or
scale deposits periodically, at least once every year before
start of each heating season� When soot is present on
section walls and flueways, improper combustion will result,
causing additional sooting and scaling until flueways are
completely closed. To remove soot and scale from flueways,
remove top jacket panel, top clean-out plate, open burner
swing door� See Figure #22�
Periodic inspection and tightening of tankless heater/cover
plate bolts will reduce risk of leaks�
