WARNING
!
Improper installation, adjustment, alteration, service
or maintenance could result in death or serious
injury.
Boiler is equipped for residential installations. If used for
commercial applications; additional code requirements
must be adhered to. This may require additional controls,
including but not limited to manual reset low water cut off,
manual reset high temperature limit, and wiring and/or
piping modifications.
Installation must conform to the requirements of the
1.
authority having jurisdiction or, in the absence of such
requirements, to the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or Natural Gas and Propane
Installation Code, CAN/CSA B149.1.
Where required by authority having jurisdiction,
2.
installation must conform to the Standard for Controls
and Safety Devices for Automatically fired Boilers,
ANSI/ASME CSD-1.
Be certain gas input rate is correct. Over-firing may
3.
result in early failure of boiler components; this may
cause dangerous operation. Under-firing may result in
too much air for pre-mix burner causing poor or loss of
combustion.
Never vent products of combustion from this boiler to
4.
enclosed space. Always vent to outdoors. Never vent to
another room or to inside building.
Verify adequate outdoor air supply to boiler for
5.
complete combustion.
Follow regular service and maintenance schedule for
6.
efficient and safe operation.
Keep boiler area clean of debris and free from
7.
combustible materials, gasoline and other flammable
vapors and liquids.
Proper through-the-wall or through-the-roof
8.
combustion venting shall be in accordance with
materials and methods described in this manual.
Installation must comply with local codes.
Boiler and related hot water heating systems are
9.
not do-it-yourself items. Installation and service by
qualified professionals are required.
2 - SAFE INSTALLATION AND OPERATION
Installers - Follow local regulations with respect to
installation of CO (Carbon Monoxide) Detectors. Follow
maintenance recommendations in this manual. See
"Maintenance And Cleaning" on page 48.
Boiler Sizing
• Verify you have selected the boiler with proper capacity
before continuing installation. AHRI Rating of boiler
selected should be greater than or equal to calculated
peak heating load (heat loss) for building or area(s) served
by boiler and associated hot water heating systems. See
"Boiler Ratings & Capacities" on page 3.
• Heat loss calculations should be based on approved
industry methods.
Considerations For Boiler Location
Before selecting boiler location, consider following.
• Supplied with correct type of gas (natural gas or
propane).
• Connected to suitable combustion air intake piping
system to supply correct amount of fresh (outdoor) air
for combustion. See "Combustion Air And Vent Pipe" on
page 15.
• Connected to suitable venting system to remove
hazardous products of gas combustion. See "Combustion
Air And Vent Pipe" on page 15.
• Connected to suitable hot water heating system.
• Supplied with suitable electrical supply for all boiler
motors and controls.
• Connected to properly located thermostat or operating
control. (Not included with boiler)
WARNING
!
Fire hazard. Do not install boiler on carpeting.
Failure to follow these instructions could result in
death or serious injury.
• Placed on level surface (DO NOT install on carpeting)
• Condensate drain line must be pitched down to floor
drain or external condensate pump with reservoir at ¼"
per foot (21 mm/m) (wood frame or blocks may be used
to raise boiler).
