Venting System Termination Height

These termination heights are necessary in the interest of safety and do not ensure draft-free operation. Trees, buildings, adjoining roof lines, adverse wind conditions, etc., may create a need for a taller venting system termination should down drafting occur.

Note: The appliance and its individual shutoff valve must be disconnected from the supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psi (3.5 kPa). The appliance must be isolated from the gas supply piping system by closing the individual manual shutoff valve during any pressure testing of the gas supply piping sys- tem at test pressures equal to or less than 1/2 psi (3.5 kPa).

STEP 3 - Double Checking

When construction of the entire vent system has been completed, double check to make sure all venting sections and termination caps are unob- structed. Exhaust gases are extremely hot.

When you have chosen a horizontal termination, be sure there are no possible future obstructions from trees, bushes, snow drifts, etc. A cap shield can be purchased to help prevent possible con- tact.

STEP 4- Gas line installation

Install the gas line piping up to the right side of the appliance. A separate shut-off gas valve (supplied) should always be used. See Figure 17.

WARNING!

ALTHOUGH EACH UNIT IS LEAK TESTED IN THE FACTORY, IT IS MANDATORY FOR YOU TO CHECK FOR LEAKS DURING THE FIRST BURN, DUE TO HANDLING THAT IS BEY0ND THE CONTROL OF HEATILATOR DUE TO SHIPPING, INSTALLATION , AND THE LIKE. EVERY JOINT INCLUDING THE VALVE, PILOT, FITTINGS, ETC., MUST BE CHECKED TO ENSURE NO LEAKS HAVE OCCURRED.

STEP 5 - Gas Line Connection

Gas connections can be made from within the appli- ance by removing the lower panel. Connect the gas line to the appliance manual valve inlet, using 1/2" pipe. To ease installation, a listed flexible connector and manual shut-off valve are supplied. The manual shut-off valve should be connected directly to the pipe, within the fireplace control area. All connec- tions must be checked for leaks with a soap and water solution or a leak detector.

Bleed the gas line to extract any air that may have been trapped inside the pipe.
