BURNER ORIFICE CONVERSION - Slope style burners 8b. On model BVP42FP3 series fireplaces, you will have a

rectangular slope style burner. To gain access to the main orifice, disconnect the gas supply tubing at the air shutter.

9b. Remove the orifice holder from the air shutter, then remove the NG orifice.

10b.Replace the removed NG orifice with the new LP orifice designated in the orifice reference chart for your fireplace model. Secure the new orifice and replace the orifice/orifice holder back into the air shutter and secure.

11b.Loosen the air shutter screw and reset the air shutter opening in accordance with the dimension shown in the reference chart for the appropriate model fireplace.

PILOT ORIFICE CONVERSION

12.Locate the pilot assembly.

13.Pull upward on the round pilot flame hood to remove.

14.Using a 5/32" Hex Allen wrench, remove the pilot orifice, then replace with the new pilot orifice marked #35.

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

15.Refer to log placement found in your fireplace installation manual to place logs onto the burner assembly.

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

17.Turn on the gas supply. Turn on the electrical supply to the appliance. Check for gas leaks using a 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.

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

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

20.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.

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

22.Remove the manometer or pressure gage. Tighten the screw in the pressure tap.

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

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

25.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.

26.Test operation of fireplace once again. Allow the fireplace to operate for at least 10 minutes and check flame coloration. Flame 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.

The burner flame and pilot flame must be checked for proper flame characteristics, as outlined in this manual.

V E R I F Y I N G I N P U T R AT E O F C O N V E RT E D FIREPLACE

The input of the fireplace must be checked as follows:

1.Turn off all other gas appliances. Clock the gas meter and determine the number of seconds required to consume one cubic foot of gas.

2.3600 ÷ time (in seconds) = cu. ft. per hour.

3.Then cu. ft. per hour x heating value of gas = input rate (BTU/Hr). On installation without gas meters, check manifold for proper pressure.

Note: The rate noted on the data plate is measured after 45 minutes of continuous operation and adjusted for test conditions such as temperature, and barometric pressure. The above procedure is a check for correct conversion only.

PLACEMENT OF GAS CONVERSION LABEL Conversion label 2139 is to be filled out completely and placed with the data plate attached near the valve.

If the appliance has not been installed, or a warranty card has not been returned to Empire Comfort Systems, Inc., check off type of gas converted to on card (for reference once the unit is installed). Also, indicate conversion by adding "Conv." behind gas.
