NOTICE: A qualified gas appliance installer must connect the appliance to the gas supply. Consult all local codes before installation. Use new black iron pipe, steel pipe, copper tubing, or internally tinned copper tubing. Copper or internally tinned copper tubing can only according to the National Fuel Gas Code, section 2.6.3, providing gas meets sulfide limits, and where permitted by local codes. Gas piping system must be sized to provide minimum inlet pressure at the maximum flow rate (BTU/Hr).
LOG PLACEMENT FILLING THE BURNER PAN Fill the burner pan with vermiculite to the bottom of the rear log and sloped to the front edge of the burner pan.

OPERATING INSTRUCTIONS FOR SPK KITS SAFTEY INSTRUCTION FOR MANUAL CONTROL (SPK) WARNING FOR YOUR SAFETY READ BEFORE LIGHTING If you do not follow these instruction exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. BEFORE OPERATING 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. WHAT TO DO IF YOU SMELL GAS: • Do not attempt to light any appliance.
OPERATING INSTRUCTIONS FOR MVVK KITS NOTICE MILLI-VOLT CONTROL LIGHTING INSTRUCTIONS The milli-volt control does not come preassembled with an on/off switch so that it may be customized for the specific application with a wall switch, remote, etc. A switch/remote must be connected to enable the burner to light. 1. 2. 3. 4. STOP! Read the safety information label. Make sure the manual shutoff valve is fully open.
OPERATING INSTRUCTIONS FOR MANVK KIT WARNING WARNING SAFTEY INSTRUCTION FOR MANUAL CONTROL WITHOUT PILOT If you do not follow these instruction exactly, a fire or explosion may result causing property damage, personal injury or loss of life. FOR YOUR SAFETY READ BEFORE LIGHTING A. BEFORE OPERATING 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.
FLAME APPEARANCE CHECKING BURNER FLAMES Flame should be yellow and extend vertically (not curling toward fireplace screen). Ember bed should have a yellow/orange glow Figure 36 - Flame Appearance PILOT FLAME APPEARANCE The pilot flame must always be present when appliance is operating. It should just touch the top of the thermocouple/ thermoplate tip.
FIREPLACE DRAFT TEST IMPORTANT: Fireplace Draft Test During Initial Installation It is critical to verify that your chimney is drafting properly because the fireplace and gas logs function as a system. WARNING Although Monessen Hearth systems goes to great lengths to design vented gas log sets that minimize sooting, all vented log sets will soot over time. Sooting normally appears as areas of black powder-like substance on the logs.
REMOTE CONTROL RECEIVER REPLACEMENT The remote control receiver and batteries are very sensitive to heat. Exposure to high temperatures can cause the receiver to malfunction and shorten the life of the batteries. If your fireplace does NOT have a restrictive barrier (see page 6), such as glass doors, it is recommended that the remote receiver be affixed to the right hand side of the heat shield or placed in the front, right corner of the fireplace.
