III - RULES fOR SAfE InSTALLATIOn And OPERATIOn

ImPORTAnT:

Failure to follow these instruc

tions could cause a malfunction of the boiler

and result in death, serious bodily injury, and/or

property damage. For assistance or additional

information, consult a qualified installer, service

agency, or the gas supplier.

II - SAfETy SymBOLS And wARnInGS

This  appliance  has  been  equipped  for  resi-
dential  installations.  If  used  for  commercial
applications, any and all additional code  re-
quirements  must  be  adhered  to  for  installa-
tion.  This  may  require  additional  controls,
including  but  not  limited  to  an  external  wa-
ter cut off, a manual reset high temperature

limit, and wiring and/or piping modifications.

The manufacturer is not responsible for any

field installation changes made to a boiler

installation which are not described or ac-
knowledged in this manual.

WARNING

ndicates an imminently hazardous situation

which, if not avoided, will result in death,
serious injury or substantial property dam-
age.

DANGER

Indicates a potentially hazardous situation
which, if not avoided, could result in death,
serious injury or substantial property dam-
age

WARNING

Indicates a potentially hazardous situation

which, if not avoided, could result in minor or

moderate injury or property damage

CAUTION

Indicates special instructions on installation,

operation or maintenance which are important

but not related to personal injury hazards.

NOTICE

The following defined symbols are used throughout this manual to notify the reader of potential

hazards of varying risk levels.

Check all applicable state and local building

codes and utility company requirements before

installation. This installation must conform with

these requirements in their entirety. In the ab

sence of these codes, use NFPA installation

codes and good industry practice.

Before servicing the boiler, allow it to cool. Al

ways shut off any electricity and gas supply con

nected to the boiler prior to servicing.
Inspect gas line for leaks.

Be certain gas input rate is correct. Overfiring

may result in early failure of the boiler compo

nents. This may cause dangerous operation.

Underfiring may result in too much air for the pre-

mix burner causing poor or loss of combustion.
Never vent the products of combustion from this

boiler to an enclosed space. Always vent to the

outdoors. Never vent to another room or to in

side a building.
Be sure there is adequate outdoor air supply to

boiler for complete combustion.
Follow a regular service and maintenance sched

ule for efficient and safe operation.
Keep boiler area clean of debris and free of com

bustible and flammable materials.
Proper through-the-wall or through-the-roof com

bustion venting shall be in accordance with the

materials and methods described in this manual.

Installation must comply with local codes.
