SP SERIES GAS FEED TUBE INSTALLATION

SP4, SP5 and SP6 model heaters are supplied with a gas feed to be in the controls area beneath the lid. The gas
feed shall be installed on to the heater gas valve and tested for leaks.
For Universal heaters install the gas feed tube as follows:
a. Change the pop (duct connection) locations as required. This ensures the pre-cut blanking plate is removed from
the correct cabinet panel.
b. Remove the pre-cut blanking plate covering the hole in the upper corner of the end panel near the gas valve
assembly.
c. Position the gas feed tube from the gas valve out through the hole.
d. Install the compression fitting to the valve assembly to connect the feed tube. Do not over-tighten the compression
fitting.
