ReaR wall VenT applICaTIon
When installed as a rear vent unit this appliance may be
vented directly to a termination located on the rear wall
behind the appliance.
•
Only Vermont Castings Group approved venting com-
ponents are approved to be used in these applications
(Refer to ‘Venting Components’ listed for different in-
stallation requirements).
•
The maximum horizontal distance between the rear of
the appliance (or end of the transition elbow in a cor-
ner application) and the outside face of the rear wall is
0” (508 mm).
Figure 14
•
Only one 45° elbow is allowed in these installations.
•
Minimum clearances between vent pipe and combus-
tible materials are as follows:
Top - 3” (76 mm)
- except at outside wall 1" (5 mm)
Sides - 1” (5 mm)

noTe:
When using flex vent, the opening will have to be
measured according to the 1” (5 mm) rise in 4” (610
mm) vertical run.
Combustible walls:
Cut a 9

Step 3
Measure the horizontal length requirement for the venting
including a ” (51 mm) overlap, i.e. from the elbow to the
outside wall face plus ” (51 mm).
Figure 15
Step 4
Install the 4” (10 mm) vent to the appliance collar and
secure with 3 sheet metal screws. Install the 7” (178 mm)
vent pipe to the appliance collar and secure with 3 sheet
metal screws. It is not necessary to seal this connection.
If a 45° elbow is being used attach the elbow to the appli-
ance in the same manner then attach the venting to the
elbow.
It is critical that there is no downward slope
away from the appliance when connecting
the vent or elbow.
Step 5
Guide the venting through the vent hole as you place the
appliance in its installed position. Guide the 4” (10 mm)
and 7” (178 mm) collar of the vent termination into the
outer ends of the venting. Do not force the termination. If
the vent pipes do not align with the termination, remove
and realign the venting at the appliance flue collars.

instruction sheet supplied with the termination.
