Instructions / Assembly
1. Penetrating a combustible wall requires the use of a Wall Thimble. (If the wall is non-combustible, the
Vent pipe may be mortared in directly without using a wall thimble.) Install Wall Thimble into wall,
observing the aforementioned rules and/or local building codes. Select the point of wall penetration
where a minimum 1/4" per foot of slope (6.4mm per 305mm) can be maintained.* A framed opening is
required to insert the thimble halves. The Wall Thimble can be adjusted for different wall thickness.
Caulk around outside edges of plates as necessary and fasten to wall using suitable screws or nails.
The Vent Pipe must be sealed at Wall Thimble as per code regarding continuous vapor barrier.

2. Apply a continuous bead of Z-Vent High Temperature Silicone to the flange of the Garage Heater Vent
Pipe Connector so that it forms a seal when attaching the 12" Appliance Vent Adapter (
do not
tighten
locking band on the Garage Heater side of the 12" Appliance Adapter completely at this time.)
3. Using the joint procedure described on Page #3, assemble the female end of the 3' Vent Pipe to the
Screened Vent Termination Tee, and slide through the Wall Thimble from the exterior. Slip the Gear
Clamp over the end of the Vent Pipe as it passes through the interior portion of the Wall Thimble, and
connect Vent Pipe to the 12" Appliance Vent Adapter. Once all connections are made, make sure that
the Screened Vent Termination Tee is positioned horizontally.
N
ote
:
The length of the Vent Pipe may be cut on the male end using aviation snips or a hacksaw (24 tpi).
The cut end must be filed or sanded smooth before joining.
The minimum length of the venting system must be 3 ft.
N
ote
:
The Gear Clamp must be installed around the Vent Pipe on the interior of the wall to secure pipe in
position so that the system remains stationary. (This applies to both combustible and non-combustible
walls.) See illustration on Page 5
4.
Verify that all joints are connected properly. Tighten all Locking Bands (including the locking band
from step #2 above) and the Gear Clamp. Allow 1 hour for the High Temperature Silicone to cure
before using the Garage Heater.
When the previous installation procedures are completed, examine the entire venting system to verify that
all joints are secure and sealed correctly. The seams and joints must be checked for tightness prior to using
the venting system.
The installation must conform to the requirements of the Hamilton WGH Garage Heater instructions, the
National Fuel Gas Code and Federal, State, and Local codes and regulations.
Once installation is complete, read the Limited Lifetime Warranty and mail in the Warranty Registration Card.
