ISOLATING RELAY
(SEE NOTES)
NOTES:
1. ISOLATING RELAY MAY BE ELIMINATED IF LINE VOLTAGE
SUPPLY TO FURNACES IS THE SAME PHASE .
TO VERIFY PHASING:
A) VERIFY SOURCE IS EXACTLY THE SAME EITHER L1, L2,
OR L3 FROM THE SAME TRANSFORMER OR
B) CHECK WITH SCOPE OR PHASE METER
C) IF IN DOUBT USE RELAY
2. IF ISOLATING RELAY IS NOT USED, CONNECT FURNACE “W” TERMINALS TOGETHER.

• Connection method must be in compliance with
CSA B149.1-15.
Connect the furnace to the building piping by one of
the following methods:
–
–
Aluminum alloy tubing must not be used in
exterior locations. In order to seal the grommet
cabinet penetration, rigid pipe must be used to
reach the outside of the cabinet. A semi-rigid
connector to the gas piping may be used from
there.
• Use listed gas appliance connectors in accordance
with their instructions. Connectors must be fully in
the same room as the furnace.
• Protect connectors and semirigid tubing against
physical and thermal damage when installed. Ensure
aluminum-alloy tubing and connectors are coated to
protect against external corrosion when in contact
with masonry, plaster, or insulation, or subjected to
repeated wetting by liquids such as water
The gas piping may enter the left or right side of the furnace
cabinet. The installer must supply rigid pipe long enough to
reach the outside of the cabinet to seal the grommet cabinet
penetration. A semi-rigid connector to the gas piping can be
used outside the cabinet per local codes. 1/2” NPT pipe and
-
hook shaped manifold, a 2” long nipple is required.
A semi-rigid connector to the gas piping can be used outside
location of union and cabinet width. The union may be
placed inside or outside of the cabinet.
