Models
3. Place the blower against the lower rear wall of the rebox outer
wrapper with the exhaust port directed upward and the thermodisc
positioned up near the replace bottom. The thermodisc must be
oriented near the replace bottom as shown in Figure 28, page 15,
in order to sense temperature and properly operate. The blower
will be held in position against the back wall by the magnets
incorporated onto the blower housing (see Figure 28, page 15).
4. Be certain that all wire terminals are securely attached to ter-
minals on blower motor and thermal switch, and that the screw
for the thermodisc bracket and green ground wire is tight.
5. Mount the speed control box against the mounting plate provided
in the lower replace cavity by placing the plastic control shaft
forward through the round hole (see Figure 26, page 15).
6. While supporting speed control, secure control shaft with lock
nut by pushing and turning lock nut with pliers clockwise until
it is tight against mounting plate. Place control knob provided
on shaft (see Figure 26, page 15).
7. Check to make sure that the power cord is completely clear of
the blower wheel and that there are no other foreign objects in
blower wheel. Also double check all wire leads and make sure
wire routing is not pinched or in a precarious position. Correct
accordingly.
8. Turn on power to duplex outlet if previously turned off per the
warning in column 2, page 14.
9. Plug in blower power cord to duplex outlet.
10. The blower will only run when the speed control knob is in the
ON position and the thermal switch senses temperature after the
replace begins to heat up. The blower speed can be adjusted by
rotating the control knob. To turn off, turn knob fully counterclock-
wise until it clicks off. If the blower is ON and has been running
with the replace operating, the blower will continue to run for a
short time after the replace has been turned off. As the thermal
switch cools down, the blower shuts down automatically.
11. Peel off the backing paper and stick the supplied wiring diagram
decal on the rebox bottom approximately 12" in front of the
blower (see Figure 27, page 15).

pane/LP supply.
Installation Items Needed
Before installing replace, make sure you have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved exible gas line with gas connector (if allowed by local
codes)
* A CSA design-certied equipment shutoff valve with 1/8" NPT tap
is an acceptable alternative to test gauge connection. Purchase the
CSA design-certied equipment shutoff valve from your retailer.
For propane/LP connection only, the installer must supply an
external regulator. The external regulator will reduce incoming
gas pressure. You must reduce incoming gas pressure to between
11" and 14" of water. If you do not reduce incoming gas pressure,
replace regulator damage could occur. Install external regulator
with the vent pointing down as shown in Figure 30. Pointing the
vent down protects it from freezing rain or sleet.
Internally-tinned copper tubing may be used in certain
pipe is too small, undue loss of volume will occur.
