Placement and System design:
The first thing that needs to be done is deciding where and
how the boiler will be installed.
Things that need to be taken into consideration are the
intended use of the boiler. For example, is the boiler going
to be used as a secondary or backup heating system? If it
is to be used in conjunction with an existing oil or gas boiler
system will it be piped in parallel or in series? The answers
to these and other questions can be determined by talking
to your certified dealer or a qualified HVAC or plumbing
contractor. This will ensure that the boiler is installed and
piped to best accommodate your needs and expectations.
Much consideration must be given to the venting. Due to low
exhaust gas temperatures, the boiler should be placed where
the venting system can be as short as possible. Pay particular
attention to electrical connection needs and combustible/
service clearance requirements.
After the boiler is set into place the venting can be installed.
Make sure any exhausting devices or appliances used in the
area are installed so as not to create negative pressure in
the room where the boiler is located.
This boiler must not be installed in an area or room where
chemicals or solvents are used or stored in quantities above
that of normal use.
Installation
Floor Protection:
The striped area indicates the minimum required floor
protection area if the boiler is going to be placed on a
combustible floor.
Special Note: When installing on a
protected floor, the levelling feet need to be adjusted
so that the bottom of the unit is 1¼ inches off the floor
protector (see illustration below).
This boiler requires 46⅞”
X 29⅛” (48⅞ X 29⅛ in Canada) of non combustible floor
protection as shown above. 16” (US) or 18” (Canada) of the
floor protection must be in front of the boiler as shown, with
6” extending on either side. CSA/CAN B366.1 requires floor
protection extending 2” (50mm) under horizontal section of
chimney connector. Floor protection must be a minimum of
26 gauge sheet metal.
Minimum non-combustible floor protection area
Levelling feet must be adjusted to give
1¼ in of clearance when installing
boiler on a protected combustible floor.
Note:
It is recommended that the levelling feet be installed in all
installations. The air space provided will help to prevent
condensation or trapped moisture which may lead to rust on
the bottom of the unit.
The feet can be adjusted using a 7/16” open end wrench.
This appliance is also approved for installation into a
shop.
