Section 6: MAINTENANCE
6.1 INTRODUCTION
Properly maintained, your boiler will provide
years of dependable, trouble free service. It is
recommended
that
a
regular
routine
maintenance program be established and
followed by the user. Components are subject to
eventual failure that requires service. Failure to
use the correct procedures or parts in these
circumstances may make the unit unsafe or
reduce the life of the boiler. The owner should
have the following inspection and maintenance
procedures performed:
6.1.1 At all times
An immediate inspection should be made if:
An odor of melted plastic or overheated
material is detected
A leak coming from the unit or the
heating system is observed
If a leak is detected at the outlet of the safety
relief valve, it could be related to a problem with
certain components installed on your heating
distribution system. A quick correction is then
required.
Do not plug the outlet of this safety relief valve if
a dripping condition occurs.
6.1.2 Twice a year
Check for the proper operation of the
automatic air purger(s) and eliminate air
from the radiators.
6.1.3 Annually
It is recommended that a visual
inspection be made on the electrical
compartments of the boiler to check the
water tightness of the gasket on the
element flange and also check for any
signs of overheating of the components
and wires. Required corrections should
be made as soon as possible.
Parts used for replacement should be
the same as the original equipment.
Make sure that the power on the unit has
been turned off before opening the electrical
compartments of the boiler.
Close isolating valves and clean the
strainer located on the heating return
piping.
Open the boiler drain valve to eliminate
deposits that could have settled at the
bottom of the boiler. Stop when water
gets clear. If there is no flow or a very
small flow, it could be due to a large
accumulation of deposits at the bottom
of the unit. If so, close the isolating
valves at the inlet and outlet of the
boiler, remove heating element(s) and
clean the inside of the tank with a
strong jet of water.
