INSTALLING YOUR ROOM HEATER 
HORIZONTAL EXHAUST VENT INSTALLATION 
1.  Locate your appliance in a location which meets the requirements of this manual 
and where it does not interfere with the house framing, wiring, etc.. 
2.  Install a non-combustible hearth pad underneath the unit. This pad should extend 
at least 6” (152 mm) in front of the unit. 
3.  Place the stove approximately 15” (381 mm) away from the interior wall. 
4.  Locate the center of the exhaust pipe of your unit. This point should then be 
extended to the interior wall of your house. Once you have located the center 
point, on the interior wall, cut a 7” (175 mm) diameter hole through the wall. 
5.  The next step is to install the wall thimble, refer to the instructions which come 
with the wall thimble for this step. 
6.  Install the appropriate length of exhaust vent pipe into the wall thimble. See step 
11 when determining the correct length of exhaust vent to use. 
7.  Install the optional combustion air intake pipe. The unit has an option to utilize 
outside air for combustion. Be sure that the outside air vent has a proper cap on it 
to prevent rodents from entering and also is installed where it won’t become 
blocked with snow, etc.. 
8.  Connect the exhaust vent pipe to the exhaust outlet of your appliance. 
9.  Secure all vent joint connections with 3 screws. Seal the exhaust vent joint 
connections with high temperature silicone sealant. 
10. Push the unit straight back to the interior wall but be sure to maintain the 
minimum clearances to combustibles 6” (152 mm) to the back of the unit. Seal 
the annular space, of the wall thimble, around the vent pipe with high temperature 
silicone sealant. 
11. The exhaust vent pipe must extend at least 12” (300 mm) out past the exterior 
wall. Seal the annular space, of the wall thimble, around the vent pipe with high 
temperature silicone sealant. 
12. Install a listed horizontal termination cap or if necessary install a 90° elbow and 
appropriate length of vertical venting. A listed vertical vent cap is recommended 
however (if local codes allow) when the vent terminates several feet above ground 
level and there are no trees, plants, etc. within several feet a 45° elbow can be 
used as a termination. The elbow must be turned down to prevent rain from 
entering.
