Brick Panel Installation - Regency L540E Owners & Installation Manual

STANDING PILOT AND HEAT EXCHANGE RETURN
The L540E / HZI540E use a heat exchanger and efficient combustion
technology to provide extreme heating efficiencies. The more efficient an ap-
pliance becomes, the lower the flue gas temperatures becomes.
On start-up, flue temperatures are required to initiate venting action.
Here are some considerations when setting up the L540E / HZI540E:
1) When operating the unit in temperatures below 50° F, run the pilot in
"Standing Pilot" mode, by setting the Surefire™ switch to ON.
The switch is located to the bottom left of the Firebox Door.
Move the switch to the right to run in Standing Pilot mode, to the left to
run in Intermittent Pilot (electronic ignition) mode. This will aid in keeping
the flue slightly warmer than the outside air, making start up a smoother
process.

2) The "Heat Exchanger Return"may be installed in circumstances where
the maximum efficiency is desired. This will require that the unit is run in
standing pilot mode only, as the Heat Exchanger return presents
additional restriction to the flue system.

INSTALLING THE HEAT EXCHANGER RETURN
1) Remove the left and right side panels. Remove one screw in the upper
left and upper right of the firebox as shown below. Once the screws
have been removed, lower the front edge of the exhaust baffle and pull
towards you. There are 3 screws at the rear of the exhaust baffle that
help to position the baffle and keep it straight during operation.
2) If the unit has been previously operated, spray the fasteners with WD-40
and let them sit for a few minutes. Remove the screw that holds the heat
exchange return in place. Insert the Heat Exchanger Return up inside
the head exchanger. Some clearance holes are provided to fit around
existing fasteners. re-install the screw(s) that will hold the Heat Exchang-
er Return in place. Re-install the Exhaust Baffle and Panels.
