Installation / Operation Instruction Manual

The FT Series Wall Mounted, Combination Boiler
Page 21
4.5 General Location Guideline
1. Vent system installation must be in accordance
with Local codes or, in the absence of local codes,
the National Fuel Gas Code, ANSI Z224.1 /NFPA
54 and/or CSA B149.1, Natural Gas and Propane
Installation Code.
2. The Boiler is designed to be installed as a Direct
Vent (sealed combustion) type. The air for
combustion must be supplied directly from the
outside to the burner. Also, the ue gases must be
vented directly to the outdoors (through wall or roof).
3. Do not install venting system components on the
exterior of building except as specically required by
these instructions
- Vent terminals must be at least 1 foot from any door,
window, or gravity inlet into the building.
- Maintain the correct clearance and orientation
between the vent and air intake terminals.
The vent and air intake terminals must be at the
same height and their center lines must be spaced
apart 12˝ minimum.
- The bottom of the vent and air intake terminal must
be at least 12˝ above the normal snow line. In no
case should they be less than 12˝ above grade
level.
WARNING
Failure to vent this Boiler in accordance with these
instructions could cause a re, resulting in severe
property damage, personal injury or death.
Do not interchange vent systems or materials unless
it is specied.
The use of thermal insulation covering pipe and
ttings is prohibited.
Do not apply an electric damper, draft hood or vent
damper with this Boiler.
Do not locate vent termination where exposed
to prevailing winds. Moisture and ice may fall
on surface around vent termination. To prevent
deterioration, surface must be in good repair
(sealed, painted, etc.).
- Do not install the vent terminal directly over
windows or doors.
- Air intake terminal must not terminate in areas that
might contain combustion air contaminates, such
as near swimming pools.
- For sidewall venting, the minimum horizontal
distance between any adjacent individual Module
(Boiler) vent terminations is twelve (12) inches. It
is better to be far more than 12 inches for avoiding
frost damage to building surfaces where vent
terminations are placed.
- The minimum horizontal distance between any
adjacent individual module (boiler) roof vent end
piece is one (1) foot.
be from a certied manufacturer.
4 . Vent system components must not be
mixed with alternate manufacturers
certied components and/or unlisted
components.
5 . The venting must be installed according
to the vent manufacturers installation
instructions.
The unit’s vent can terminate through the roof, or
through an outside wall.
Vent pipe must pitch upward, toward the vent
terminal, not less than 1/4” per foot, so that
condensate will run back to the FT to drain. Route
vent pipe to the boiler as directly as possible.
Seal all joints and provide adequate hangers as
required in the venting system manufacturer’s
Installation Instructions. Horizontal portions of
the venting system must be supported to prevent
sagging and may not have any low sections that
could trap condensate. The unit must not support
the weight of the vent pipe.
The vent shall not terminate:
- over public walkways:
- near so󰀩t vents, crawl space vents or other
areas where condensate or vapor could create a
nuisance or hazard, or cause property damage: or
- where condensate or vapour could cause damage
or could be detrimental to the operation of
regulators, relief valves or other equipment.
