BBV, SBV Series Natural Vent Gas Fireplaces
CHECKING GAS PRESSURE
1. Check gas type. The gas supply must be the same as stated on the appliance’s rating decal. If
the gas supply is different from the fireplace, STOP! Do not install the appliance. Contact your
dealer immediately.
2. To ease installation, a 30” (762 mm) flex line with manual shut-off valve has been provided with
this appliance. Install and attach 1/2” gas line onto shut-off valve.
3. After completing gas line connection, purge air from gas line and test all gas joints from the gas
meter to the fireplace for leaks. Use a solution of 50/50 water and soap or a gas sniffer.
4. To adjust flame height, turn HI/LO knob to HI to get maximum pressure to burner. Turn HI/LO
knob to LO to get minimum pressure.
5. To check gas pressures at valve, turn captured screw counterclockwise 2 or 3 turns and then
place tubing to pressure gauge over test point. Turn unit to high. Figure 16. After taking pressure
reading, be sure and turn captured screw clockwise firmly to reseal. Do not over torque. Check
test points for gas leaks.
WARNING
Do not use open flame to check for gas
leaks.
