Resolute Gas Heat – Fifth Edition – October 2015

Carlin burners has a smooth interior. If the amulet is a tight fit on the burner head, then slightly moisten inside the amulet
with water.
Place a 3/8" bead of retort cement onto the burner head at the flange to air tube joint, and slide the (moistened) amulet
over the burner head and against the flange. Ensure proper seating of the amulet by pressing the amulet onto the burner
with a flat object. Leave the excess retort cement at the amulet to flange joint and the cement will provide an airtight seal of
the air tube flange to the boiler face.
The Carlin amulet does not have an edge and when fully seated the amulet will be flush with the front of the Carlin
burner head. If needed, trim the front edge of the amulet to be flush with the front of the burner head.
Once the amulet has been seated and trimmed, then install the burner into the boiler by carefully inserting the air tube
with amulet into the boiler opening while aligning the burner flange holes with the boiler studs. Install flat washers and nuts
onto the boiler studs and tighten all nuts evenly.
GAS BURNER SETTINGS
EK-1 Resolute Gas Boilers are shipped from the factory preset for 100,000 Btu/Hr firing rate. The following table lists
approximate settings for Carlin EZ-Gas burners based on extensive testing.
CAUTION:
Final settings for a particular installation
must
be determined by using combustion test equipment and following

GAS PIPING SYSTEMS
The boiler and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure
testing of the gas supply piping system at test pressures in excess of 1/2 psi (3.5 kPa, 14 in wc).
The boiler must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any
pressure testing of the gas piping system at test pressures equal to or less than 1/2 psi (3.5 kPa, 14 in wc).
A manual shut off valve and a sediment trap must be provided in the gas piping upstream of the electric combination
gas valve at the boiler. The boiler and its gas connection must be tested for gas leakage before placing the boiler in
operation.
Gas piping must be properly sized in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or
according to state and local codes as applicable. Gas piping must be sized to provide the maximum firing rate gas flow for
all appliances in the building. For Natural Gas installations, be sure to verify that the gas meter is properly sized for all
appliances. Do not use any service 90
o
elbows. Use only full port shutoff valves. If in doubt, oversize the piping.
BEST PRACTICE:
Always size piping based on natural gas pipe size guidelines.
