codes, ANSI Z223.1 (National Fuel Gas Code Publication No. NFPA-54). Where ASME CSD-1
is required by local jurisdiction, the installation must conform to CSD-1.
Where applicable, the equipment must be installed in accordance with the current Installation
Code for Gas Burning Appliances and Equipment, CGA B149, and applicable Provincial
regulations for the class. Authorities having jurisdiction should be consulted before installations
are made.
See the last two pages of this chapter for important information regarding installation of units

WARNING!
• Do not use matches, candles, flames, or other sources of

• Prior to installing this product read all instructions included in
this manual and all accompanying manuals/documents. Perform
all installation steps required in these manuals in the proper
order given. Failure to adhere to the guidelines within these
manuals can result in severe personal injury, death or
substantial property damage.
• Fluids under pressure may cause injury to personnel or damage
to equipment when released. Be sure to shut off all incoming
and outgoing water shutoff valves. Carefully decrease all
trapped pressures to zero before performing maintenance.
• Before attempting to perform any maintenance on the unit, shut
off all gas and electrical inputs to the unit.
• The exhaust vent pipe of the unit operates under a positive
pressure and therefore must be completely sealed to prevent
leakage of combustion products into living spaces.
• High electrical voltages are used in this equipment, therefore
the cover on the unit’s power box must be installed at all times,
except during maintenance and servicing.
