Figure 4: Cara DR Control Panel.

The air shutter is controlled by sliding the air shutter adjustment screw (shown in Figure 5) either forwards or backwards. The adjustment screw, for the primary air, is located on the bottom of the rebox. The air shutter nut can be accessed by removing the control panel. This is best done during the initial installation.

Sliding the shutter forwards increases the primary air while sliding the shutter backwards decreases the primary air.

The air shutter allows the amount of air coming into the replace to be adjusted in order to accommodate different climates and venting arrangements. Start the pilot and then the burner. Make sure the pilot ame is burning normally and none of the burner ports are plugged. Let the replace burn for roughly fteen (15) minutes and then examine the ames, compare the ames to Figure 43 or Front Cover.

Figure 5: Air Shutter Adjustment.

Operating Instructions

For Your Safety, Read Safety Precautions

And Lighting Instructions Before Operating

The ideal ame will be blue at the base and light orange above. The ames should be of medium height. If the ames look like this (refer to Figure Figure 43 or Front Cover), no adjustment is needed. If the ames are fairly short and mostly blue, the replace is getting too much air. Therefore, the air shutter should be closed slightly until the correct ames are achieved. Flames that are very orange, with tall, dark, stringy tips, are not getting enough air. Open the air shutter until the ames clean up. If the shutter is opened, or closed all the way, and the correct ames cannot be attained, turn off the gas and contact the dealer.

Warning: Incorrect air shutter adjustment may lead to improper combustion, which is a safety hazard. Contact the dealer if there is any concern about the venturi adjustment.

b. Remove the four (4) ” screws that hold the

ue collar elbow to the unit body.

c. Carefully remove the elbow being sure not to

damage the gasket that is glued to the ue collar elbow, it seals the ue to the rebox (see Figure 25).

d. Turn the elbow 180° to the rear vent position

and re-fasten with the screws removed in step b.

2. This unit has been shipped with a Cara

orice installed and it must be replaced with a Cara DR orice (NG - PO512-42 DMS or LP

- PO512-54 DMS). Refer to MAINTENANCE AND SERVICE - FUEL CONVERSION.

3. Set the appliance in the desired location. Check to determine if wall studs are in the way when the

venting system is attached. If this is the case, you may want to adjust the location of the appliance.

4. Direct vent pipe and ttings are designed with special twist-lock connections. Assemble the desired

combination of black pipe and elbows to the appliance adapter with pipe seams oriented towards the wall or oor, as much out of view as possible.

Place a bead of Mil-Pac on the outer edge of the inner exhaust pipe

(non-ared end). Place a bead of high temperature silicone on the male edge of the outer pipe. Push the pipe sections completely together, then twist-lock one section clockwise approximately  turn, until the two (2) sections are fully locked. The female locking lugs will not be visible from the outside, on black pipe. They may be located by examining the inside of the female ends as shown in Figure 26.

Notes: (a) Twist-lock procedure: four (4) indentations, located on the female end

of the pipes and ttings, are designed to slide straight onto the male ends of adjacent pipes and ttings, by orienting the four (4) pipe indentations so they match and slide into the four (4) entry slots on the male end.

(b) Pipe minimum clearances to combustibles must be maintained; 2” (51mm) at top, 1” (38mm) at sides, 1” (38mm) at bottom.

3. With the pipe attached to the stove in the correct location, mark the wall for a 10” (25.4cm) x 10”

(25.4 cm) square hole (refer to Figure 27). The center of the square hole should match the center line of the horizontal pipe. Cut and frame the 10” (25.4cm) x 10” (25.4cm) hole in the exterior wall where the vent will be terminated. Refer to Figure 24 and Table 7. If the wall being penetrated is constructed of non-combustible material i.e. masonry or concrete, a 7” (17.8cm) hole is acceptable.

4. Position the horizontal vent termination in the center of the 10” (25.4cm) x 10” (25.4cm) hole, and

attach to the exterior wall with the four (4) screws provided. Before attaching the vent termination to the exterior wall, run a bead of non-hardening mastic around the edges, so as to make a seal between

(b) For buildings with vinyl siding, a vinyl siding standoff, should be installed between the vent cap and the exterior wall (see Figure 29). Attach the vinyl siding standoff to the horizontal termination. The vinyl siding standoff prevents excessive heat from possibly melting the vinyl siding material. Note that the horizontal vent termination bolts onto the at portion of the vinyl siding standoff (shaded area in Figure 29), so that an air space will exist between the wall and the vent termination.

(c) The horizontal run of vent pipe must be level and should have a 1 inch (32mm) rise for every one foot (305mm) of run towards the termination. Never allow

the vent to run downward. This could cause high temperature and may present the possibility of a re.

(d) The location of the horizontal vent termination on the exterior wall must not be easily blocked or obstructed.

(e) When installing a vent pipe in a chase the minimum clearance to combustibles is 2” (51 mm).

(f) Maintain manufacturer’s clearances to combustibles with venting.

24. No dealer, distributor, or similar person has the authority to represent or warrant VistaFlame products beyond the terms contained within the Limited Warranty. Sherwood Industries Ltd. assumes no liability for such warranties or representations.
