This DV Power Vent System was certified by CSA  
to be used only with CFM Corporation Direct Vent  
models, as listed in this manual.  
All 4” and 7” venting connections (twist-lock or  
crimped ends) to be sealed with high temperature  
silicone.  
This DV Power Vent System can be used with any  
CFM Corporation side wall vent termination kits,  
vertical vent termination kits or snorkel kits (rear vent  
termination not to be used).

tion.  
Maximum TOTAL allowable system length is 40FT  
of straight pipe, plus up to five 90 degree elbows.  
Any combination of 45 and 90 degree elbows up to a  
maximum of 450 degrees is allowed. It is NOT per-  
missible to substitute elbows for length of horizontal  
or vertical straight pipe.  
When the DV Power Vent box is installed in a con-  
fined area, the access door needs to have a mini-  
mum size of 12” X 12” and it must be ventilated with  
a minimum of 10% open area. In a confined area  
installation a minimum distance of 12” (1FT), needs  
to be left between the Power Vent Box and the fifth  
wall. (Refer to Figures on Page 5).  
Can be vented down to a maximum of 12FT, meas-  
ured from the center line of the highest section to the  
centre line of the lowest section between the fireplace  
and the DV Power Vent box.  
When the DV Power Vent box is installed in an un-  
confined area, the access door doesn’t need to be  
ventilated.  
Minimum vent length of straight pipe between fire-  
place and the DV Power Vent box is:  
The power vent motor shaft MUST ALWAYS BE ori-  
ented horizontally for proper operation.  
10 feet for units with input up to 33,000BTU/h;  
15 feet for units with inputs from 33,000BTU/h  
to 40,000BTU/h.  
The pressure switch diaphragm MUST ALWAYS BE,  
in a vertical position and the hose connection point-  
ing down, NEVER up.  
Maximum vent length of straight pipe between the  
DV Power Vent System box and the vent termination  
is 6 FT.  
Disconnect power supply when installing or servicing  
the fireplace or the power vent system.

3- DV Power Vent System Setup:  
3.1 - Checking the Pressure Switch Position:  
The pressure switch diaphragm must be in a vertical plane.  
The pressure switch hose connections should NEVER point up. The BEST position is pointing down, but can  
be pointed to the sides.  
Depending on the final location of the DV Power Vent System box, the pressure switch hose connection needs  
to be checked. If the hose connection position needs to be adjusted, follow these steps:  
1. Check the pressure switch location;  
2. If the hose connection is pointing down, you do not need to change the pressure switch position;  
3. If the hose connection location needs to be adjusted, remove the two screws holding the pressure switch to  
the bracket.  
4. Rotate the pressure switch clockwise or counterclockwise (whichever is better to reach the new position);  
5. Re-attach the pressure switch to the bracket with the same screws removed in Step 4.  
6. Check all wire connections according to the wiring diagram.  
7. Check hose connections between the pressure switch and the blower. Make sure the hose is not kinked.  
(Refer to Figure A)  
3.2 - Wire Connections:  
Remove one screw and one nut that are holding the circuit board cover in place. (Refer to Figure B) Bring  
the cover, with the circuit board, the power cord and all the existing wires attached to it, to a rest position.  
(Refer to Figure C)  
Make all connections between the DV Power System box and the unit according to the wiring diagram. Use  
18 gauge AWS wire with minimum 2/64” insulation.  
For connections to the circuit board, use 3/16” Quick Connect female spade terminals, all others are  
screwed connections.  
The DV Power Vent System can be hard wired. To hard wire the DV Power Vent System, disconnect the  
power cord from the circuit board and replace it with hard wiring according to the connections shown in the  
wiring diagram.

3.3 - Adding Deflectors to the Side Wall Vent Termination:  
1. Open the plastic bag and check all components.  
(One Top Deflector, one Bottom Deflector, four self-tapping screws)  
2. Install the bottom deflector using two screws provided with the kit. Refer to Figure A.  
3. Open the top screen and install the top deflector. Refer to Figure B. Attach the top deflector using two screws  
provided with the kit.  
4. After installing the top and bottom deflectors the vent termination should look like Figure C.  
5. Close the top screen to the same way it was before.

DV Power Vent System  
Operation of the DV Power Vent System  
Turn the switch ON/OFF or the wall thermostat, to the ON position.  
Blower will start immediately and will purge the unit and the vent system for 45 seconds. At that point, the pilot will light  
and the main burner(s) will follow.  
When the switch ON/OFF or the wall thermostat, is turned to OFF, the main burner and the pilot will shut-down immedi-  
ately and the blower will run for 45 seconds to clear the flue gases before turning OFF.  
If the unit is ON but the flame is unstable (ON and OFF continuously), turn the switch to the OFF position and call a  
serviceman to check the installation.  
Maintenance  
The DV Power Vent System box is a maintenance free system. The motor bearings are pre-lubricated for extended life  
and no further lubrication is required.  
It is recommended however to have the system checked once a year by a qualified professional.

DV Power Vent System  
Changing the Orifice Plate After the DV Power Vent Box is Installed  
If there is a need to change the restrictor plate orifice on the DV Power Vent System box, follow the steps below:  
A. Turn the power OFF to fireplace and power vent.  
B. Remove the blower’s cover (two parts):  
Remove the hose attached to the blower casing.  
Remove two screws. Refer to Figure A.  
Remove two nuts from the right side cover.  
Remove the right side cover by pulling it out. Refer to Figure B.  
Remove two nuts from the left side cover.  
Remove the left side cover by pulling it out. Refer to Figure C.  
C. Remove the two nuts that hold the pressure switch bracket. Do not disconnect any wire or the hose. Just bring the  
pressure switch still attached to the bracket to a rest position, to give you access to the screws that hold the blower  
bracket. Refer to Figure D.  
D. Disconnect the wires from the blower.  
E. Remove the four screws that hold the blower bracket. Be careful not to drop the blower.  
F. Slide down the blower to release it from the top extrusion and carefully bring the sub-assembly (blower with the bracket  
and the gasket) to the outside of the box to replace the orifice; Be careful not to damage the gasket, otherwise you  
will have to replace it. Refer to Figure E.  
G. Remove the two 3/8” nuts holding the orifice plate. Refer to Figure F.  
H. Get from the orifice plate kit the correct restrictor orifice size for the unit you are installing (check chart for restrictor  
orifice size X unit model).  
I. Install the correct orifice plate into the same location as the previous one.  
J. Place back the two nuts.  
K. Reinstall the blower. Make sure the exhaust of the blower is properly inserted into the opening.  
L. Re-attach the blower bracket with the four screws removed in step “C”.  
M. Connect the wires to the blower (see wiring diagram).  
N. Re-attach the pressure switch to the original position and secure the two nuts removed in step “B”.  
O. Re-install both covers to the blower:  
Install the left side and secure it with the nuts.  
Install the right side and secure it with the nuts.  
Re-attach the two screws.  
Re-attach the hose to the blower connection.  
P. Check all wires according to the wiring diagram and the hose connections to make sure everything is properly  
in place.
