Selecting Location To determine the safest and most efficient location for your appliance, you must take into consideration the following guidelines: 1. The location must allow for proper clearances (see Clearances). 2. Consider a location where heat output would not be affected by drafts, air conditioning ducts, windows, or doors. 3. A location that avoids the cutting of joists or roof rafters will make installation easier. Figure 2 shows a plan view of a few common locations.
Pre-Installation Preparation Continued 1" (2.5 cm) Min. Clearance to "B" Vent's Outer Pipe Ceiling 42" (10.67 cm) Min.

Pre-Installation Preparation Continued FRAMING 1. Frame appliance enclosure as illustrated in Figures 7 and 8. Note: If a wall covering is used to line the enclosure, then all measurements must be from the surface of the covering. 2. Place the appliance into the framing and secure it. Note: If appliance is to be raised above floor level, a platform must be built to support the appliance. 3.
Venting INSTALLATION Continued Example 1 shows the minimum allowable system height and lateral offset for a 60° or greater inclination. Code specifies that offsets at 60° or greater are considered horizontal and must follow the 75% rule for lateral to total vertical system height. Codes also allows only one offset in the total system when at 60° or greater.
Venting INSTALLATION Continued Some codes areas allow the use of existing Btype vent systems if the system is at or above the recommended diameter of the flue. The flue connection must be made using listed B-type connectors and the existing system must be code inspected for damage and proper installation. It is not recommended that this appliance be common vented with an existing gas burning appliance.
INSTALLATION Continued WARNING: Do not wire remote wall switch to main power supply (standard 120V household current). 3. Locate wall switch in a convenient location. 4. After wire connections are complete, replace refractory access panel. OUT O ON IN FF Note: If any original wire as supplied must be replaced, use 18 AWG TYPE CL2 (UL) 105° C (25 ft. length MAX) or equivalent.
INSTALLATION Continued Installing 9-Volt Battery in Hand-Held Remote Control Unit 1. Remove battery cover on back of remote control unit. 2. Attach terminal wires to battery (not included). Place battery into battery housing. Note: Only use alkaline battery. 3. Replace battery cover onto remote control unit.
INSTALLATION Continued Before connecting the black iron gas line to the inside of the appliance a sediment trap must be included outside the appliance between the gas line and the gas shutoff valve. It must extend down 3" beyond the center of the pipe. Prepare incoming black iron gas line with Teflon tape or pipe joint compound (Check with local building codes).
INSTALLATION Continued 4. Place just enough to cover the entire surface and leave about a 1/2" gap under the lower grate members to allow air to flow (see Figure 24). Grate Vermiculite (Pan Material) Burner Pan Figure 22 - Fill Entire Burner Pan with Vermiculite (P325/VP325 Models Shown) Ember Material Grate Vermiculite (Pan Material) Burner Pan 2. Insert pegs on bottom of rear log into holes in rear of grate (see Figure 25). 3.
INSTALLATION Continued LOG PLACEMENT For P325(B)/ VP325(B) Models 1. Place rear log onto grate making sure notches rest over grate (see Figure 27). 2. Place front right log onto front right side of grate with back of log fitting into notch on right front of rear log (see Figure 27). 3. Rest front of front left log between first two grate fingers on left of grate assembly and rear into notch on left front of rear log (see Figure 28). 4. Place top of log 4 into notch on log 1.
INSTALLATION Continued COMBUSTION AIR KIT MODEL AK4 (OPTIONAL) The outside air kit may be installed on the left side of the fireplace only. The vent can be installed through the outside wall or a ventilated crawl space. The handle to operate the damper door for the outside air inlet will be located inside the left “screen pocket” of the firebox (see Figure 31). Pull the handle to open or push to close. CAUTION: Air inlet ducts are not to terminate in attic space.
INSTALLATION Continued 7. To adjust doors, slide them partially open. Using a screwdriver, loosen the holddown screws in spring clip (see Figure 34) and pivot plate. 8. Close both doors until evenly joined at the middle and note gap at outer edges of face. 9. Reopen one door at a time and retighten upper and lower hold-down screws. 10. Repeat process until both doors are evenly joined, spaced and working freely. CAUTION: Glass panels become very hot while the appliance is operating.
Operation FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
Operation Continued TO TURN OFF GAS TO APPLIANCE 1. Turn off wall switch (if installed). 2. Turn off all electric power to appliance if service is to be performed. 3. Fully open glass doors if installed. 4. Remove front hearth brick and control access panel. 5. Turn gas control knob clockwise to OFF. Do not force. 6. Replace front refractory brick access panel. 7. Fully close glass doors if installed.
Inspecting Burners Continued BURNER FLAME PATTERN Burner flames will be steady; not lifting or floating. Flames should go up through the middle of log set. Flames should not "spill" to the edges of the pan or sides of the log set. P324 and VP324 Models Figure 39 shows a typical flame pattern.
Troubleshooting Note: Before troubleshooting the system, make sure the gas shutoff valve is ON. The two most common causes of a malfunctioning gas appliance are: 1. Loose wiring connections 2. Construction debris clogging the pilot and/or gas control valve filter OBSERVED PROBLEM POSSIBLE CAUSE REMEDY Pilot will not light 1. No gas supply, or shutoff 1. Check to see if you have valve is OFF gas supply 2. Air in gas line 2.

Check for spark at the after repeated triggering of at electrode) electrode and pilot; if no red button spark and electrode wire is properly connected, replace ignitor 2. Defective pilot or mis- 2. Using a match, light pilot.
TROUBLESHOOTING Continued WARNING: If you smell gas • Shut off gas supply. • Do not try to light any appliance. • Do not touch any electrical switch; do not use any phone in your building. • Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions. • If you cannot reach your gas supplier, call the fire department. IMPORTANT: Operating fireplace where impurities in air exist may create odors.
