GENERaL iNStRUctiON FOR SEaSONaL StaRtUP & 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.
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation.
CAUTION
!
Verify proper operation after service.
If the venter has oil cups, lubricate venter motor once a month
during the heating season with a few drops of non-detergent
motor oil (SAE 20 or 30). Replace the rubber plugs when
finished.
DO NOt OVER OiL.
CAUTION
!
BEGiNNiNG OF EacH HEatiNG SEaSON
Before seasonal start-up, it is highly advisable to have a
1.
certified service agency inspect the system:
Check the boiler for soot and scale build up in the flues.
A.
Clean the burners.
B.
Check the gas input rate to maintain high operating ef

C.
ficiency.
The service agency should make certain the system is
2.
filled with water to minimum pressure (approximately 12
pounds per square inch) 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 venting system at the start of each heating sea

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. Periodic cleaning of the
5.
condensate collection system is required. When a con
-
densate collection system is installed in a venting system,
it is recommended that the cleaning become a part of the
annual servicing.

FOLLOWS:
Remove tubing from condensate tee.
A.
Empty all liquid from tubing.
B.
Rinse tubing inside & out in a sink with water.
C.
If tubing cannot be cleaned inside, the tubing should be
D.
replaced with the same type and size of tubing.
Replace tubing as described in

. (Fill trap
with water.)
Visually inspect entire piping system and if any leaks

appear, have them repaired as soon as possible. DO
NOT use petroleum based stop leak compounds.
check venter assembly static pressure as fol-

lows:
With the boiler off, disconnect the white compression
A.
fitting on the pressure switch.
Connect a slope manometer to the compression fitting
B.
with additional tubing.
Turn the boiler on and read suction pressure on the
C.
manometer. Reading should be negative (-) .55 ± .05
inches of water column or higher for the 50B thru 150B
and negative (-) .65 ± .05 inches of water column or
higher for the 200B.
If static pressures are not at the minimum allowable level

(listed above), check vent pipe for obstructions.
