Section 5: MAINTENANCE
5.1 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 require 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:
5.1.1 At all times
An immediate inspection should be made if:
An odor of melted plastic or overheating
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.
Never plug the outlet of this safety relief
valve if a dripping condition occurs
.
5.1.2 Twice a year
Check for the proper operation of the
automatic air purger(s) and eliminate air
from the radiators using their manual air
purger.
5.1.3 Annually
It is recommended that a visual
inspection be made on the electrical
compartments of the boiler to check the
seal of the gasket on the element flange
and also check for signs of overheating
on 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 turn off before opening the electrical
compartments of the boiler.
Close required isolating valves and
clean the strainer (if used) located on the
heating return piping.
Open the boiler drain valve to eliminate
deposits that could have settle 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
spray of water
