REFER TO SPECIFICATION TABLE AND INSTALLATION MANUAL FOR PROPER USAGE
The following instructions apply to Canadian installations in addition to installation and operating instructions:
1. Installation must conform with local building codes, or in absence of local codes, with current CSA B149.1 installation codes for natural gas
burning appliances and equipment, or CSA B149.2, installation codes for propane gas burning appliances and equipment.
2. Any references to U.S. standards or codes in these instructions are to be ignored and the applicable Canadian standards or codes applied.
3. The reducer must be fi eld supplied for 100, 125, 150 and 175 MBH unit sizes.
4. If using a metal vent system under positive gauge pressure in Canada, a slip fi t vent connection must be secured by at least two corrosion-
resistant screws, or other mechanical locking means.
5. The vent shall not terminate – (a) Less than 6 ft. (1.8m) from a combustion air inlet of another appliance. (b) Less than 3 ft. (1m) from any
other building opening or any gas service regulator. (c) Directly above a gas utility meter or service regulator.
Use single wall pipe constructed of 26 gauge galvanized
steel or material or equivalent durability and corrosion
resistance for the vent system. For installation in
Canada, vent pipe must conform with local building
codes, or in absence of local codes, with current CSA
B149.1/B149.2 installation codes for gas bur ning
appliances and equipment.
Never use a pipe of a diameter
other than that specified in Table 1 or Figure
2! Never use PVC or other nonmetallic pipe for
venting! To do so may result in serious damage
to the unit or severe personal injury or death!
The vent terminal must be installed with a minimum
clearance of four feet (1.2m) from electric meters, gas
meters, regulators and relief equipment.
Seal ALL vent pipe joints and seams to prevent
leakage. Use General Electric RTV-108 or Dow-
Corning RTV-732 silicone sealant (or equivalent); or 3M
#425 aluminum foil tape (or equivalent).
The vent system must be installed to prevent collection
of condensate. Vertical vent pipes should be equipped
with condensate drains. Pitch horizontal pipes
downward 1/4 inch per foot (21mm per meter) toward
outlet for condensate drainage (refer to Figures 9
through 16).
Horizontal por tions of the venting system shall be
supported at maximum intervals of four feet (1.2m)
to prevent sagging (in Canada, support at 3 feet (1m)
minimum intervals).
Insulate single wall vent pipe exposed to cold air or
running through unheated areas.
Each unit must have an individual vent pipe and
vent terminal per furnace section! Each unit MUST
NOT be connected to other vent systems or to a
chimney.
Units are shipped from the factory set up for vertical
venting. To conver t the power venter for horizontal
venting, remove the shipping support bracket; refer to
Figures 9 thru 12 and 22, and follow this procedure:
1. Hold power venter motor in position.
2. Remove the three Phillips-head screws from the
motor adaptor plate.
3. Remove the three screws which connect the
power venter stack to the power venter housing.
4. Rotate the power venter housing to the horizontal
position.
5. Replace screws accordingly.
NOTICE: The motor, pressure switch, and junction
box bracket MUST remain located as shipped from
the factory. Rotate only the blower housing! If the
power venter housing is to be moved to the right
horizontal position, the junction box must be rotated
90 degrees CCW to clear the connection. To do this,
remove all wires, conduit and conduit connector
from the junction box, noting location of wires. Move
box, using holes provided. Move 7/8 inch plug from
bottom of box to side. Reconnect all wires according
to the unit's wiring diagram.
