Maxitrol Valve Conversion

DIRECT IGNITION PROPANE/LP GAS CONVERSION

1.Turn off the gas supply.

2.Turn off the electrical supply to the appliance if so equipped.

3.Open or remove glass doors if applicable.

4.Remove top louver and lower bottom louver.

5.Remove logs from burner assembly.

VALVE CONVERSION

6.Remove plastic cap from regulator ﬁtting. Unscrew ﬁtting using a 7/16" wrench. Turn ﬁtting over so end of ﬁtting marked "LPG" is visible. Tighten ﬁtting (snug only). Replace plastic cap.

7.Remove 1/4" screw from air shutter.

8.Located to the right of electrodes is a burner hold-down tab. Using needle-nose pliers, bend burner hold-down tab off the main burner.

9.Remove main burner by pivoting main burner forward as you slide main burner from left to right. Be careful as you remove main burner in order to protect the electrodes from being damaged.

10.Remove air shutter from oriﬁce ﬁtting.

11.Remove natural gas main burner oriﬁce from oriﬁce ﬁtting.

12.Install propane/LP main burner oriﬁce marked 1.35mm for BVD34FP50, marked 1.45 mm for BVD36FP52, or marked 1.65mm for BVP42FP52.

Important: Failure to install the correct oriﬁce will result in unit over-ﬁring that could overheat the appliance and result in a ﬁre.

13.Replace air shutter onto oriﬁce ﬁtting. Air shutter must be threaded and bottomed-out onto oriﬁce ﬁtting.

14.Replace main burner onto burner assembly. Place main burner beneath electrodes, slide main burner from right to left into burner location, and pivot main burner away from you and into air shutter.

15.Set air shutter opening as indicated by the chart below. Tighten air shutter in place with 1/4" screw from step 7.

16.Using needle-nose pliers, bend burner hold-down tab over main burner.

17.Refer to log placement, pages 14 and 15 to place logs onto burner assembly.

Model	AIR SHUTTER	BURNER ORIFICE
	SETTINGS
	Opening "A"	Propane/LP Oriﬁce
BVD34	5/16" (8mm)	1.35mm
BVD36	5/16" (8mm)	1.45mm
BVP42	Full Open	1.65mm

18.Loosen screw and attach a manometer or pressure gauge to the outlet pressure tap of the control valve.

19.Turn on the gas supply. Turn on the electrical supply to the appliance. Check for gas leaks using soap and water solution or leak detection solution. Bubbles indicate a leak that MUST be corrected. Do not use an open ﬂame to test for gas leaks.

20.Check the air shutter opening. See chart and illustration below.

21.Relight the main burners and verify proper burner ignition and operation.

22.With the main burner burning, read the pressure on the manometer or pressure gauge. The pressure on the gauge should read between 9.8" and 10.2" w.c.

23.Turn off the gas supply. Turn off the electrical supply to the appliance.

24.Remove the manometer or pressure gauge. Tighten the screw in the pressure tap.

25.Turn on the gas supply. Turn on the electrical supply to the appliance.

26.Immediately test all gas line connections and the control valve for gas leaks using a soap and water solution or other gas detection solution. Bubbles indicate a leak that MUST be corrected. Do not use an open ﬂame to test for gas leaks.

27.Using a ball point pen, ﬁll out the conversion label that is supplied with the conversion kit. Place the conversion label adjacent to the rating plate.

28.Test operation of ﬁreplace once again. Allow the ﬁreplace to operate for at least 10 minutes and check ﬂame coloration. Flames on rear of burner should be yellow without any orange-colored tip. Minor adjustment of the air shutter may be necessary to "tune in" the proper ﬂame color.
