Installation & Operation Manual
3 General venting
16
Requirements for installation in
Canada
1. Installations must be made with a vent pipe system
certified to ULC-S636.
IPEX is an approved vent manufacturer in Canada
supplying vent material listed to ULC-S636.
2. The first three (3) feet of plastic vent pipe from the
appliance flue outlet must be readily accessible for visual
inspection.
3. The components of the certified vent system must not be
interchanged with other vent systems or unlisted
pipe/fittings. For concentric vent installations, the inner
vent tube must be replaced with field supplied certified
vent material to comply with this requirement.
4. The 3 and 4" Concentric Vent Kit available from
Lochinvar (see Section 4 – Sidewall Termination –
Optional Concentric Vent) and the 3 and 4" Concentric
Vent Kit available from IPEX are both approved for use
on the Armor wall mount water heater. Both kits are
listed to the ULC-S636 standard for use in Canada.
Model Kit Number
Equivalent Vent
Length
125 - 200 100140480 3 feet
Table 3A Concentric Vent Kit Equivalent Vent Lengths
Minimum / Maximum allowable combustion
air and vent piping lengths are as follows:
Combustion Air = 12 equivalent feet minimum / 100 equivalent
feet maximum
Vent = 12 equivalent feet minimum / 100 equivalent feet
maximum
When determining equivalent combustion air and vent length,
add 5 feet for each 90° elbow and 3 feet for each 45° elbow.
EXAMPLE: 20 feet of PVC pipe + (4) 90° elbows + (2) 45°
elbows + (1) concentric vent kit (100140480) = 49 equivalent
feet of piping.
The appliance output rating will reduce by
up to 1.5% for each 25 feet of vent length.
NOTICE
Sizing
The Armor wall mount water heater uses a 3 inch combustion
air intake and vent pipe. The maximum length of each one is
100 feet.
Increasing or decreasing combustion air or
vent piping sizes is not authorized.
NOTICE
Air inlet pipe materials:
The air inlet pipe(s) must be sealed. Choose acceptable
combustion air inlet pipe materials from the following list:
PVC, CPVC, Polypropylene or ABS
Dryer Vent or Sealed Flexible Duct (not recommended for
rooftop air inlet)
Galvanized steel vent pipe with joints and seams sealed as
specified in this section.
Type “B” double-wall vent with joints and seams sealed as
specified in this section.
AL29-4C, stainless steel material to be sealed to
specification of its manufacturer.
*Plastic pipe may require an adapter (not provided) to transition
between the air inlet connection on the appliance and the plastic
air inlet pipe.
⚠WARNING
Using air intake materials other than those
specified can result in personal injury, death
or property damage.
NOTICE
The use of double-wall vent or insulated
material for the combustion air inlet pipe is
recommended in cold climates to prevent
the condensation of airborne moisture in the
incoming combustion air.
Sealing of Type “B” double-wall vent material or galvanized vent
pipe material used for air inlet piping on a sidewall or vertical
rooftop Combustion Air Supply System:
a. Seal all joints and seams of the air inlet pipe using either
Aluminum Foil Duct Tape meeting UL Standard 723 or
181A-P or a high quality UL Listed silicone sealant such as
those manufactured by Dow Corning or General Electric.
b. Do not install seams of vent pipe on the bottom of
horizontal runs.
c. Secure all joints with a minimum of three (3) sheet metal
screws or pop rivets. Apply Aluminum Foil Duct Tape or
silicone sealant to all screws or rivets installed in the vent
pipe.
d. Ensure that the air inlet pipes are properly supported.
The PVC, CPVC, or ABS air inlet pipe should be cleaned and
sealed with the pipe manufacturer’s recommended solvents
and standard commercial pipe cement for the material used.
The PVC, CPVC, ABS, Dryer Vent or Flex Duct air inlet pipe
should use a silicone sealant to ensure a proper seal at the
appliance connection and the air inlet cap connection. Dryer
vent or flex duct should use a screw type clamp to seal the vent
to the appliance air inlet and the air inlet cap. Proper sealing
of the air inlet pipe ensures that combustion air will be free of
contaminants and supplied in proper volume.
Follow the polypropylene manufacturer’s instructions when
using polypropylene material as an inlet pipe.
When a sidewall or vertical rooftop combustion air supply
system is disconnected for any reason, the air inlet pipe
must be resealed to ensure that combustion air will be free of
contaminants and supplied in proper volume.
⚠ DANGER
Failure to properly seal all joints and seams
as required in the air inlet piping may
result in flue gas recirculation, spillage
of flue products and carbon monoxide
emissions causing severe personal injury
or death.
