High Elevations
Input ratings are shown in BTU per hour and are 
certified without deration for elevations up to 
4,500 feet (1,370m) above sea level.
For elevations above 4,500 feet (1,370m) in USA, 
installations must be in accordance with the cur-
rent ANSI Z223.1/NFPA 54 and/or local codes hav-
ing jurisdiction.
In Canada, please consult provincial and/or local 
authorities having jurisdiction for installations at 
elevations above 4,500 feet (1,370m).
Gas Line Installation
When purging the gas lines, the front win-
dow frame assembly must be removed.
The gas pipeline can be brought in under the bottom of 
the fireplace. The gas line connections will be covered 
by bottom trim. Refer to Figure 7 for gas line dimen-
sions. Use 1/2” rigid pipe. When gas line is in place un-
der the fireplace, install supplied 1/2” FPT to 3/8” flare 
brass fitting. Connect preinstalled flex line on fireplace 
to brass fitting with 3/8” flare fitting on supply line.  
The gas line connection can be made with 3/8” rigid 
pipe or an approved flex connector. Since some munici-
palities have additional local codes, it is always best to 
consult your local authority and the National Fuel Gas 
Code, ANSI Z223.1/NFPA 54 in the USA or the CSA-
B149.1 installation code.
Remote ON/OFF Hi/Lo 
Wall Mounted Transmitter
The DVR28 is equipped with a wireless transmitter. No 
wires are required.
Always check for gas leaks with a mild 
soap and water solution applied with a 
brush no larger than 1” (25 mm). Never 
apply soap and water solution with a spray 
bottle. Do not use an open flame for leak 
testing.
The fireplace valve must not be subjected 
to any test pressures exceeding 1/2 psi. 
Isolate or disconnect this  or any other gas 
appliance control form the gas line when 
pressure testing.
The gas control is equipped with a captured screw type 
pressure test point, therefore it is not necessary to pro-
vide a 1/8” test point up stream of the control.
When using a flex connector use only approved fittings. 
Always provide a union when using black iron pipe 
so the gas line can be easily disconnected for burner 
servicing. See gas specification for pressure details and 
ratings.
The fireplace valve must not be subjected to any test 
pressures exceeding 1/2 psi. Isolate or disconnect this 
and any other gas appliance control from the gas line 
when pressure testing.
