WARNING

Failure to follow all precautions could result in fire, explosion or death!

removing the cap and installing the manometer. The gas pressure must remain between 7" and 14"

during stand-by (static) mode and while in operating (dynamic) mode. If an in-line regulator is used,

it must be a minimum of 10 feet from the Munchkin. It is very important that the gas line is prop-

erly purged by the gas supplier or utility. Failure to properly purge the lines or improper line siz-

ing, will result in ignition failure. This problem is especially noticeable in NEW LP installations and

also in empty tank situations. This can also occur when a utility company shuts off service to an area

to provide maintenance to their lines. This gas valve must not be replaced with a conventional gas

valve under any circumstances. As an additional safety feature, this gas valve has a flanged con-

nection to the Venturi and blower.
