any door, opening window or gravity air inlet into any building. It shall also have a minimum horizontal clearance of four feet from any electric meter, gas meter, regulator, relief valve or other equipment.

-The vent terminal shall be located not less than seven feet above grade when it is adjacent to public walkways.

-The bottom of the vent terminal shall be located at least twelve inches above grade or ground or the normally expected snow accumulation level.

The snow level may be higher on walls exposed to prevailing winds.

-Avoid areas where local experience indicates that condensate drippage may cause problems, such as above planters, patios, public walkways or areas where condensate or vapor could cause a nuisance or hazard, or where its discharge could be detrimental to the operation of regulators, relief valves or other equipment.

GAS PIPING

The gas inlet pipe size is 3/4 inch NPT, male thread, located at the lower right front corner of the appliance. The gas supply piping must be sized to adequately provide the input BTU/hr rate for the appliance at the specified flowing pressure (see table 1). The maximum inlet gas pressure must not exceed the maximum value shown in table 1. The minimum gas pressure shown in Table 1 is for purposes of input adjustment.
