VENTING
Clearance to combustibles
The following clearances must be maintained around the vent pipe:
Vertical runs: 1”
Horizontal runs: 2” on top, 1” sides and bottom
IMPORTANT: This appliance venting system is a sealed system (DV), which means that all combustion
air is supplied from outdoors and the combustion products are exhausted to the outdoors.
Note: Only venting systems listed in this manual may be used with the model 57-DVRS50
Planning your vent installation
This type of direct vent system may terminate in one of two ways: vertical termination using a vent cap, or
horizontally using a wall termination. There are limitations to the vertical and/or horizontal lengths (see
page 18 for venting chart).
When calculating the length of the vent pipe from the outlet of the appliance to termination, allowing for
ceiling thickness, the vertical rise in the attic or second story and sufficient vertical height above the roof.
Fire stops are required at each floor level the vent passes through.
The following vent systems are certified for use with the model 57-DVRS50
If for any reason the vent pipe is disconnected it must be correctly resealed

Install as per manufactures instructions

57-DVRS50 15
Installation Instructions Cont.
The position of the horizontal vent termination
must be positioned in such a way as to meet all
local building codes.
Cut and frame the exterior wall to accept the
Wall Thimble. Install the Wall Thimble shield
using wood screws. If the wall being penetrated
is constructed of non-combustible material con-
crete or block wall a 8” hole sufficient for the
vent pipe is acceptable.
Venting terminals must not be recessed
into wall or siding
When the termination is to be attached to vinyl siding apply a bead of non-
hardening mastic around the outside edge to form a seal between the
standoff and the terminal. Attach the termination to the exterior wall using four wood
screws through the holes in the corners.
Complete the termination installation and apply a bead of mastic around the outer edge
of the vinyl standoff.
With the termination installed you can now connect the completed vent assembly by
sliding the unit back towards the wall and carefully inserting the pipe into the terminal.
Slide the pipe into the vent, making sure that at least 1¼” overlap between the pipe
and the termination.
N O T E
ALLOWING THE VENT PIPE TO SLOPE DOWN TOWARDS THE VENT TERMINA-
TION WILL CAUSE POOR COMBUSTION AND/OR HIGH TEMPERTURES THAT
MAY PRESENT A FIRE HAZARD.

Restrictor
Note: The model 57 DVRS50 is sup-
plied with an adjustable restrictor. The
restrictor is not required for most in-
stalls. However if the flame is consid-
ered too lively, the restrictor may be
installed and adjusted to provide the
required flame picture.
Example: Using rigid pipe over 40’ may
require restriction.

Before connecting the appliance to the gas supply line, double check that the appliance you
have purchased is designed for the gas type you are using. The gas type markings are located
on the certification label and also on the appliance’s gas valve.
Adequate clearance for proper installation and checking of the gas connections must be
provided. All gas connections must be checked for gas leaks.
GAS CONNECTIONS
Have your gas supplier or a qualified gas fitter run a gas supply line into the fireplace. The line
must be properly sized and fitted according to the installation codes. Immediately upstream of the
supply connection, the fitter shall provide an accessible manual shut-off valve. When connecting
the supply line to the gas valve, the installer shall brace the gas valve to ensure that the gas valve
is not moved from its bracket. If the valve is not braced when the supply line is connected, the
valve may be moved and cause a “break” in the main burner supply line. Such damage is not
covered by the manufacturer’s warranty.
CAUTION: The appliance must be isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure-testing of the gas supply piping system at
test pressures equal to or less than 1/2 psig (3.5 kPa). Failure to do so will damage the
appliance’s gas valve. Such damage is not covered by the manufacturer’s warranty.
Natural Gas Pressure Settings:
The inlet supply or line pressure must be a minimum of 5” W.C. (1.2 kPa) and a maximum of 14”
W.C. (3.5 kPa). The orifices are a #35 DMS (2.73 mm) drill size for the center burner and #48
DMS (1.93 mm) for the two outer burners.
ELEVATION INPUT RATING
0-2,000 ft (0-610 M) 50,000 BTU/hr (14.7 kW)
2,000 ft (610 M) and above. 50,000 BTU/hr (14.7 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orifice size you require.
Propane Pressure Settings:
The inlet supply or line pressure must be a minimum of 11” W.C. (2.8 kPa) and a maximum of 14”
W.C. (3.5 kPa). The orifices are a #52 DMS (1.78 mm) drill size for the center burner and
#57 DMS (1.07mm) for the two outer burners .
ELEVATION INPUT RATING
0-2,000 ft. (0-610 M) 50,000 BTU/hr (14.7 kW)
2,000 ft. (610 M) and above. 50,000 BTU/hr (14.7 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orifice size you require.
NOTE: THE INPUT RATING SHOULD ALWAYS BE CHECKED WHEN FIRST RUNNING THIS
APPLIANCE. To do this, reduce the background flow rate, time the meter, light the fireplace and
take another reading after 15 minutes of operation. Check with your gas supplier for the gas BTU
content at your elevation. Input is the rate of flow multiplied by the heating value of the gas (cubic
feet/hour x BTU per cubic feet). Adjust the manifold pressure so that the unit does not operate
above the rated input.
IMPORTANT: For high altitude installations above 2000 ft (610 meters), consult local gas distributor or the authority having juris-
diction for proper de-rating methods.
