Installation
1. Pierce a 16mm (5/8 in.) dia. hole into the flue pipe 300mm
to 450mm (12 to 18 in.) from the breech connection of
the water heater. Remove one of the securing nuts from
the pipe of the safety switch. Tighten the other securing
nut onto the pipe as far as possible.
2. Insert the threaded pipe end into the pierced hole, then
install the securing nut, which was removed in step 1,
and tighten securely.
Caution: Turn "OFF" the electrical supply to the water heater
when wiring safety switch.
3. Wire the safety switch in series with L1 of the electrical
supply. Install and route wiring in an accordance with
“Canadian Electrical Code Part 1 (C22.1)” and any
applicable local codes.
Caution: If for any reason the system has shut down
during operation, the cause of the system failure should be
investigated and corrected before resetting the safety switch
and re-starting the system.
Power Venting
Models JW6 F307, JW6 F507 and JW F657 may be power
vented with a Field SWGII 4HD Power Venter. The following
control kits may be used with the SWGII 4HD:
CK 61 Electronic Post Purge.
CK 62 Thermally Activated Post Purge.
Installation Of Power Venter
The current edition of “Installation Code for Oil-Burning
Equipment" (B139) , local codes and the manufacturer's
instructions should be adhered to in all installations of the
water heaters and power venters. A draft regulator must be
used in conjunction with the installation of the power venter
(see "Draft Regulator"). Consult the applicable codes to
calculate the equivalent length of pipe for each fitting in the
vent system. Add this (equivalent) length to the length of the
straight runs of pipe to determine the total equivalent vent
pipe length.
