WARNING: Remove the two caps in the vet adaptors before
installing the vent terminations
Installations must comply with:
6 . 1
− Local, state, provincial, and national codes, laws, regulations
and ordinances.
− National Fuel Gas Code, ANSI Z223.1/NFPA 54 – latest edition.
− National Electrical Code.
− For Canada only: CAN/CSA B149.1 Installation Code, CSA
C22.1 Canadian Electrical Code Part 1 and any local codes.
The boiler must be installed indoors in a dry location where the
ambient temperature must be maintained above freezing and
below 100°F [38°C]. All boiler components must be protected from
dripping, spraying water, or rain during operation and servicing.
Consider the proximity of system piping, gas and electrical supply,
condensate disposal drain, and proximity to vent termination when
determining the best boiler location.
The boiler is both for closet and alcove installation.
Closet Installations
CLOSET INSTALLATION
0 in./0 mm between the back of the
unit and the wall.
Alcove Installations
Alcove installations have the same minimum clearances as closet
installations, except the front must be completely open to the room
at a distance no greater than 18 in. [457 mm] from the front of
the boiler and the room is at least three (3) times the size of the
alcove. Provided these conditions are met, the boiler requires no
extra ventilation air openings to the space.
9
CAUTION Apply the provided Warning Label and Lighting
Instructions to the front of the boiler casing if the closet or
alcove sides are less than 6" (150 mm) from the boiler right
side. Doing so will make the Lighting Instruction and Warning
Label visible for the appliance in an Alcove or Closet
Residential Garage Installation
When installed in a residential garage, mount the boiler a minimum
of 18 in. [457 mm] above the floor. Locate or protect the boiler
so it cannot be damaged by a moving vehicle. Check with your
local authorities for other possible regulations pertaining to the
installation of a boiler in a
6 .2 Before locating the boiler
Check for nearby connections to:
− System water piping
− Venting connections
− Gas supply piping
− Electrical power.
Check area around boiler. Remove any combustible materials,
gasoline and other flammable liquids.
Check water quality.

WARNING: Failure to keep boiler area clear and free of
combustible materials, gasoline and other flammable liquids
and vapors can result in severe personal injury, death or
substantial property damage.
The boiler must be installed so that gas control system components
are protected from dripping or spraying water or rain during
operation or service.
If the new boiler is to replace an existing boiler, check for and
correct any existing system problems such as:
− System leaks
− Incorrectly-sized expansion tank
− Lack of freeze protection in the heating system causing the
system and boiler to freeze and leak
− Excessive glycol which will affect the boiler system operation.
6 .3 Clearances for service access
See "5.5 Dimensions and connections" page 15 for recommended
service clearances. If you do not provide the minimum clearances
shown, it might not be possible to service the boiler without
removing it from the space.
9
WARNING: The space must be provided with combustion/
ventilation air openings correctly sized for all other appliances
located in the same space as the boiler. The boiler front
cover must be securely fastened to the boiler to prevent the
boiler from drawing air from inside the boiler room in a sealed
combustion application. This is particularly important if the
boiler is located in the same room as other appliances. Failure
to comply with the above warnings could result in severe
personal injury, death or substantial property damage.
