• Installation
Install burner & wiring and fill system
To install burner
1.
Unpack burner.
2.
Place gasket around air tube and against burner mounting flange.
If sealing rope is used, apply
around burner mounting flange and apply sealing rope to make
gas-tight seal.
3.
Mount burner into opening in burner mounting plate.
Maintain gas-tight seal between burner mounting flange
and plate to prevent damage to air tube.
4.
Level burner using burner support brackets where required.
5.
Secure with furnished bolts.
6.
Retain burner information packet. Keep with boiler.
To wire burner and boiler controls
Electric shock hazard. Can cause severe personal injury
or death if power source is not disconnected before
installing or servicing boiler and burner.
1.
Install all wiring in compliance with:
•
National Electrical Code ANSI/NFPA 70.
•
Any additional national, state, or local codes.
2.
Follow burner manual and wiring diagram found in burner in-
formation packet.
3.
Use #14 AWG wire for operating and safety circuit wiring.
4.
Where burner motor voltage differs from control voltage, supply
proper voltage to each. Size fused disconnects and conductors per
National Electrical Code ANSI/NFPA 70.
Determine if water treatment is needed
(water boilers only)
Do not use petroleum-based cleaning or sealing com-
pounds in boiler system. Severe damage to system
components can result, causing substantial property
damage.
Continual make-up water will reduce boiler life. Minerals can build up
in sections, reducing heat transfer, overheating cast iron and causing
section failure.

• Parts
For unusually hard water areas or low pH conditions
(less than 7.0) consult local water treatment company.
Provide a water softener for make-up water if hardness
exceeds 7 grains.
Freeze protection (when used)
(water boilers only)
1.
Use antifreeze especially made for hydronic systems.
Inhibited propylene glycol is recommended.
Do not use automotive, ethylene glycol
or undiluted antifreeze. Severe personal
injury or death can result.
2.
50% solution provides protection to about -30°F.
3.
Local codes may require back-flow preventer or
actual disconnect from city water supply.
4.
Determine quantity according to system water
content. Boiler water content is listed in "Ratings,"
page 35. Percent of solution will affect sizing of heat
distribution units, circulator and expansion tank.
5.
Follow antifreeze manufacturer's instructions.
To fill water boilers
1.
Close manual air vents and drain cocks.
2.
Fill to correct system pressure. Correct pressure will
vary with each installation.
3.
Starting on lowest floor, open air vents one at a
time until water squirts out. Close vent. Repeat
with remaining vents.
4.
Refill boiler to correct pressure.
To fill steam boilers
1.
Do not fill (except for leakage test) until boiler is
ready to be fired.
2.
Fill to normal waterline, halfway up gauge glass.
3.
Recommend boiler water pH 7.0 to 8.5.
