Enviro EF THERMO 28 technical manual Horizontal Through Wall Installation

Installation

HORIZONTAL THROUGH WALL INSTALLATION:

The ENVIRO EF THERMO can be vented by a couple of different methods.

1.NOTE: Use only listed type “PL” or “L” pellet venting products. Failure to use listed components may cause damage or personal injury or death.

2.Choose a location for your stove that meets the requirements stated in this manual and allows installation with the least amount of interference to house framing, plumbing, wiring, etc.

3.Install a non-combustible hearth pad underneath the unit extending 6 inches (15 cm) in front of and to the sides.

4.Place the stove 15” (38.1 cm) away from the wall. If the stove is to be set on a hearth pad, set the unit on it.

5.Locate the center of the exhaust pipe on the stove. Extend that line to the wall. Once you have located the center point on the wall, refer to pellet vent manufacturer installation instructions for the correct hole size and clearances to combustibles.

6.Install the wall thimble as per the instructions written on the thimble. Maintain an effective vapor barrier.

7.Install a 2’ or 3’ (61 or 92 cm) length of 3” (7.6 cm) or 4” (10.2 cm) listed type “PL” or “L” vent pipe into the wall thimble. The pipe should install easily into the thimble.

8.Install the fresh air intake (see the section entitled FRESH AIR CONNECTIONS).

9.Connect the exhaust vent pipe to the exhaust pipe on the stove.

10.All Joints in the vent system shall be fastened with (3) three screws. Seal the connection with high temperature silicone.

11.Push the stove straight back, leaving a minimum of 1” (2.5 cm) clearance from the back of the stove to the wall. Seal the vent pipe to the thimble with high temperature silicone.

12.The pipe must extend at least 12’ (30.5 cm) away from the building. If necessary, bring another length of pipe (PL type) to the outside of the home to connect to the first section. Do not forget to place high temperature silicone around the pipe that passes through the thimble.

13.Install a vertical pipe; or, if all requirements for direct venting are met, install vent termination. The stainless steel cap termination manufactured by the vent manufacturer is recommended. However, when the vent terminates several feet above ground level and there are no trees, plants, etc. within several feet, a 45 degree elbow can be used as termination. The elbow must be turned down to prevent rain from entering.

NOTE: Some horizontal, through the wall installations may require a “T” and 4-5 feet (1.2-1.5 m) of vertical pipe outside the building to help draft the stove. This may be required if a proper burn cannot be maintained after the stove has been tested and the airflow set. This is due to back-pressure in the exhaust, caused by the air flow around the house
