BEGINNING OF EACH HEATING SEASON
Before seasonal start up it is advisable to have a competent
1.
service agency check the boiler for soot and scale in the
flues, clean the burners and check the gas input rate to
maintain high operating efficiency and safe operation.
The service agency should make certain the system is filled
2.
with water to minimum pressure and open air vents - if
used - to expel any air that may have accumulated in the
system.
Check automatic air vents for leakage.
3.
Inspect the venting system at the start of each heating sea-
4.
son. Check the pipe from the boiler for signs of deteriora-
tion and sagging joints. Repair if necessary. Remove the
vent pipe from the boiler and check for obstructions.
Clean condensate tee & trap.
5.
Periodically check the condensate trap for water/conden-
6.
sate. The trap should always have water in it. Refill the
trap if it runs dry. If the trap runs dry then flue gasses can
escape.
GENERAL INSTRUCTION FOR SEASONAL START UP AND MAINTENANCE
It is suggested that a qualified service agency be employed to
make an annual inspection of the boiler and the heating sys-
tem. They are experienced in making the inspection outlined
below.
In the event repairs or corrections are necessary they can make
the proper changes for safe operation of the boiler.
Periodic cleaning of the condensate collection system is re-
quired. When a condensate collection system is installed in a
venting system, it is recommended that the cleaning become
a part of the annual servicing. The procedure for cleaning this
system is as follows:
Remove tubing from condensate tee.
1.
Empty all liquid from tubing.
2.
Rinse tubing inside & out in a sink with water.
3.
If the inside of the tubing cannot be cleaned, the tubing
4.
should be replaced with the same type and size of tubing.
Add water to trap before replacing.
5.
Replace tubing as described in
6.

Visually inspect entire piping system and if any leaks ap-
7.
pear, have them repaired as soon as possible. DO NOT
use petroleum based stop leak compounds.

CAUTION
Label all wires prior to disconnection when servic-
ing controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after
service.
