Please read before proceeding

Installer

Read all instructions before installing. Fol-

low all instructions in proper order to prevent

personal injury or death.

• AlsorefertoCGsVenting Supplements.

• Considerpiping and installation when determining boiler

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.

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ow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.

Glycol — potential ﬁre hazard —

Allglycolisammable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.
