Section VI: Final Adjustments
WATER TREATMENT
■
Do not use petroleum-based cleaning
or sealing compounds in boiler system.
Severe damage to the boiler will occur.
Continual make-up water will reduce boiler life. Minerals can
build up in sections, reducing heat transfer, overheating cast
iron, and causing section failure.
For unusually hard water areas or low pH conditions (less
than 7.0) consult local water treatment company.
Freeze protection (when used):
Use antifreeze especially made for hydronic systems. Inhib¬
ited propylene glycol is recommended.
Do not use automotive, ethylene glycol
or undiluted antifreeze. Severe per¬
sonal injury, death or substantial
property damage can result.
50% solution provides protection to about - 30°F.
Local codes may require back-flow preventer or actual dis¬
connect from city water supply.
Determine quantity according to system water content. Boiler
water content is listed on back cover. Remember to add in
expansion tank water content.
Follow antifreeze manufacturer's instructions.
FILLING SYSTEM
1. Close manual air vents, drain cock, and automatic air vent,
if used.
2. Fill to correct system pressure. Correct pressure will vary
with each application. Residential systems are often de¬
signed for 12 pounds of cold Fill pressure.
3. Open automatic air vent one turn, if used.
4. Open manual water feed valve.
5. a) Starting on lowest floor, open air vents one at a time
until water squirts out. Close vent,
b) Repeat with remaining vents.
6. Close manual water feed valve when correct boiler pres¬
sure is reached.
WARNING
DANGER
INSPECT BASE INSULATION
Check to make sure insulation is secure against all four sides
of the base.
WARNING
If insulation is damaged or displaced,
call service technician immediately.
DO NOT operate boiler.
Ceramic fiber material used in boiler
base insulation can cause temporary
skin, eye, and upper respiratory irri¬
tation.
Use NIOSH or MSHA approved pro¬
tection when installing or removing
this material.
TO PLACE IN OPERATION
1. Be sure boiler has been correctly filled with water.
2. Follow correct lighting/operating instructions on boiler.
For CG propane gas boilers only:
WARNING
Your propane supplier mixes ai
odorant with the propane to make it
presence detectable.
In som
instances, the odorant can fade, am
the gas may no longer have an odoi
Propane gas can accumulate at floo
level. Smell near the floor for the ga
odorant or any unusual odor. If yo
suspect a leak, do not attempt t<
light the pilot.
• Use caution when attempting to ligh
a propane pilot. This should be dom
by a qualified service technician
particularly if pilot outages ar
common.
• Periodically check the odorant lev<
of your gas.
• Inspect boiler and system at leas
yearly to make sure all gas piping i
leak-tight.
• Consult your propane supplie
regarding installation of a gas lea
detector. There are some product
on the market intended for this pui
pose. Your supplier may be able t
suggest an appropriate device.
3. If boiler starts, go to Step 5.
If boiler fails to start, go to Step 4.
4. If boiler fails to start, check for following conditions:
a) Loose connection or blown fuse?
b) Limit setting below boiler water temperature?
c) Thermostat set below room temperature?
d) Gas not turned on at meter and boiler?
e) Incoming natural gas pressure less than 5" W.C. c
propane less than 11" W.C.?
f) Access panel not secured in place?
g) If above fails to eliminate the trouble, refer to Contn
Supplement.
5. Make sure boiler goes through several normal operatin
cycles.
6. Turn thermostat or operating control to desired setting.
