 Fol-

low all instructions in proper order to prevent 
personal injury or death.

•  Also refer to CGs

•  Consider

 when determining boiler 

location.

•  Any

filed immediately against the transportation company by the 

consignee.

The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials per instructions 

on page 64 of this manual. Failure to comply could result in severe personal injury.

 

When calling or writing about the boiler— Please have the boiler model number from the boiler rating label and 

the CP number from the boiler jacket. You may list the CP number in the space provided on the Installation and

service certificate found on page 31.

Read and follow the special instructions for the Commonwealth of Massachusetts, located on page 36 of this

manual.

 

Failure to adhere to the guidelines on this page can result in severe personal injury, death or substantial 

property damage.

When servicing boiler —
•  To avoid electric shock, disconnect electrical supply before

performing maintenance.

•  To avoid severe burns, allow boiler to cool before perform-

ing maintenance.

Boiler operation —
•  Do  not  block  flow  of  combustion  or  ventilation  air  to

boiler.

•  Should overheating occur or gas supply fail to shut off, do

not turn off or disconnect electrical supply to circulator. 

Instead, shut off the gas supply at a location external to the 

appliance.

•  Do not use this boiler if any part has been under water.

Immediately call a qualified service technician to inspect 

the boiler and to replace any part of the control system and 

any gas control that has been under water.

Boiler water —
•  Do not use petroleum-based cleaning or sealing compounds

in boiler system. Water seal deterioration will occur, caus-

ing leakage between sections. This can result in substantial 

property damage.

•  Do not use “homemade cures” or “boiler patent medicines”.

Severe personal injury, death or substantial property dam-

age may result.

•  Continual fresh makeup water will reduce boiler life. Min-

eral buildup in sections reduces heat transfer, overheats cast 

iron, and causes section failure. Addition of oxygen and

other gases can cause internal corrosion. Leaks in boiler 

or  piping  must  be  repaired  at  once  to  prevent  makeup 

water.

•  Do not add cold water to hot boiler. Thermal shock can

cause sections to crack.

All glycol is flammable when exposed to high temperatures. If

glycol is allowed to accumulate in or around the boiler or any 

other potential ignition source, a fire can develop. In order to 

prevent potential severe personal injury, death or substantial 

property damage from fire and/or structural damage:

•  Never store glycol of any kind near the boiler or any poten-

tial ignition source.

•  Monitor  and  inspect  the  system  and  boiler  regularly  for

leakage. Repair any leaks immediately to prevent possible 

accumulation of glycol.

•  Never use automotive antifreeze or ethylene glycol in the

system. Using these glycols can lead to hazardous leakage 

of glycol in the boiler system.
