ASSEMBLY STEPS
The typical sequence of installation follows;
however, each installationis unique resulting in
variations to those described.
1. Construct the appliance framing.
2. Route gas supply line to appliance location.
3. Remove and affix nailing flanges to the
appliance. On _DVR5-R models install the
hood.
4. Position the appliance.
5. Install the vent system and exterior termina-
tion.
6. Millivolt Appliances — Install the operating
control switch and bring in electrical service
line for forced air circulating blower (optional
equipment).
7. Electrical Appliances —Field wire and install
operating contro! switch.
8. Mount forced air blower (optional equip-
ment).
§. Make connection to gas supply.
19. Install the logs and ember coals.
14. Checkout appliance operation.
12. install glass door frame assembly.
13. Adjust burner to ensure proper flame ap-
pearance.
INSTALLATION
The appliance is shipped with al! gas controls
and components installed and pre-wired. Re-
move the shipping carton, exposing the front
glass door frame. Remove wood slats and
remove and discard the wood slat mount brack-
ets. Loosen and remove the three (3) 14'-20 x
1" Phillips pan head screws at the three (3) tabs
located along the door frame top edge. Tilt the
glass door frame assembly outward and disen-
gage the three (3) tabs along the bottom of the
door from the three (3) brackets at the bottom
of the firebox opening. Remove the door and
set the panel aside protecting it from inadvert-
ent damage. Retain the three (3) screws for use
on reassembly. Remove the logs, bubble
wrapped and secured to the inside of the appii-
ance door, and also set aside.
Step 1. Frame appliance enclosure as illus-
trated in Figures 4 through 6.
Note: The framed depth, 15 14" (394 mm) from
a framed wail, must always be measured from
a finished surface. If a wall covering such as
drywall is to be attached to the rear wall, then
the 15 ¥2" (394 mm) must be measured from
the drywall surface. It is important that this
dimension be exact in order for the vent termi-
nal kitto be connected properly. Sirnilarly, the
29 V4" (734 mm) {41 %" (1051 mm)} framing
dimension is important for corner vent connec-
tions.
if the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed.
The header may be in direct contact with the top
metal spacers, but must not rest on them.or be
notched to fit around them.
Step 2. Route a #2‘ (13 mm) gas line along the
left or right side framing (Figure 3).
All appliances have a 3" long %° NPT nipple
installed at the valve. To quickly and easily
complete the gas line routing, use the gas flex
line kit, Model _GFLV.
Figure &
Step 3. The nailing flanges are installed at
each side of the appliance backwards when
shipped from the factory, to protect the unit
from shipping damage. Remove the nailing
flanges from the appliance and install in place
(as shown in Figure 9) with three (3) screws
each. Align with the three holes on each side
of the appliance, ensuring that the face of the
flange is in a plane ¥2" behind the appliance
front face.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Nailing Flange
Figure §
Install the hood on all__DVR5-R units*. Posi-
tion the hood in the open area just above the
appliance door. Locate the flange, found along
the top edge of the hood, behind the upper
radiant panel. Install the two (2) screws into the
holes at the ends of the hood. Secure the hood
totheappliance frame by tightening the screws.
Step 4. Position appliance into. prepared fram-
ing, secure with 6d nails at the nailing flange
along each side.
Step 5. Installing the Venting ~ The _DVR5
Series appliance must be vented directly to the
ouiside through its own double wall pipe as-
sembly; 5° (127 mm) and 8" (203 mm) diam-
eters. The vent system may not service mul-
tiple appliances and must never be connected
toa flue serving a solid fuel burning appliance.
These appliances are designed, tested and listed
for operation with, and only with, DST5 vent
components. DO NOT use other manufactur-
ers’ components.
Listed Vent Components:
_DST5-HTK ~ Horizontal termination kit
_DV-HTK-1 — - Horizontal termination kit
_DST5-FSV — Firestop
_DST5-12/18 - Vent sections
_DST5-45ELB - 45 Degree elbow
