By-Pass Damper Adjustment
The by-pass lever is adjusted at the factory, but should be checked, as correct adjustment is
essential for proper combustion. To check adjustment, push the by-pass knob in and down.
With a firm push, it should lock into place on the bracket. If the stop on the rod is engaged on
the bracket but the handle still has front to back play, or, if the handle will not push in far
enough to engage the stop, the by-pass must be adjusted. To do so, loosen the nut at the rear
of the rod and rotate the rod to tighten or loosen the adjustment. To complete the adjustment,
make sure the welded stop rod is pointed downward, and tighten the locknut.
Turbulators
Turbulators should be located in the oil or gas heat exchange tubes when the boiler is received.
Please check to be sure they are located correctly and that they are not in the wood heat
exchange tubes in error.
Installation of Back-Up Fuel Burner
Either an oil, propane gas (LPG) or natural gas (NG) burner may be used to provide back-up or
full-time heat with the EXCEL boiler.
Individual instruction manuals are provided in the box with each oil or gas burner. In addition,
the following information is necessary and important:
•
Before installing the burner, if necessary, trim the hole in the burner door brick with a
knife so that the burner can be inserted through the opening.
•
120 Volt AC power feed for the oil or gas burner is wired to “B” and “N” terminals inside
the boiler Control Panel. The “T” terminals on the burner primary control must be
connected to the #7 and #8 terminals on the 24 Volt terminal strip on the Control Panel
housing.
NOTE: 1.
IF THE OIL OR GAS BURNER IS IMPROPERLY INSTALLED, NOT
INSTALLED AND/OR NOT SERVICED ON A REGULAR BASIS, DAMAGE
TO THE BOILER MAY RESULT.
2. BURNER INSPECTION AND TUNE-UP SHOULD BE DONE NOT LESS
THAN ONCE PER YEAR BY A QUALIFIED HEATING CONTRACTOR OR
BURNER SPECIALIST. DAMAGE TO THE BOILER OR PARTS DUE TO
IMPROPER INSTALLATION MAY NOT BE COVERED UNDER WARRANTY!
Oil Burner Installation (refer to Oil Burner Manufacturer’s Instruction Manual)
If the Tarm EXCEL is to be fired on oil, a flame-retention burner MUST be used. A BECKETT
AF burner is standard equipment. Oil burners must be adjusted with test equipment, not “by
eye”. A minimum .04 in./wc draft is required. The nozzle specifications are as follows:
•
TARM EXCEL 2000
•
TARM EXCEL 2200
80
°
Delavan B--- .75 to 1.10 GPH
80
°
Delavan B--- .75 to 1.35 GPH
NOTE:
The Beckett AF burner must be equipped with an F-6 retention head for operation
with 1.10GPH or greater nozzle. An F3 head is standard with the burner. An F-6
retention head is shipped with an EXCEL 2200.
