Section: ASSEMBLE THE BURNER
Pieces of tape can be cut loose during installation and
lodge in gas valves causing cutoff seal problems.
Teflon tape lubricates pipe threads, allowing iron pipes to
penetrate too deeply into aluminum valve bodies causing
distortion and leakage.
Use only pipe sealant compounds that are resistant to
the gas being used.
Verify that the gas valve
is not damaged and that
all piping and fittings are de-burred and
clean inside and out.
Install the Valve and Manifold to the Burner
1. Determine the correct fuel orifice using the
appliance’s fuel type, firing rate and Table 5 on
Page 10, and insert it into the recess in the
manifold adapter on the top of the burner’s air tube
( Figure 10 on Page 15). Notice in Table 5 that
not all natural gas applications use a fuel orifice.
2. Lubricate the O-ring with the small packet of
lubricant provided and install it into the groove on
the bottom of the manifold mounting block.
3. You may mount the manifold assembly with the
valve on either the right or left side of the burner
( Figure 10). Tighten its screws securely.
4. Connect the violet and white wires (from the
electrical box adjacent to the air tube) to their
mating spade terminals on the top of the gas valve.
The white wire goes to the terminal marked “C” and
the violet wire goes to the terminal marked “MP”.
Propane Applications
Beckett CG4 burners are designed to fire either natural
gas or propane gas by changing only the fuel orifice
( Figure 10, Page 15). Table 5 on Page 10 lists the
correct fuel orifices for both fuels by firing rate together
with the other rate-variable components of the burner.
All the burner’s adjustments and settings for propane will
be the same as for natural gas when the appropriate fuel
restrictors are in place. For ANSI Z21.17a purposes, the
propane restrictors listed in Table 5 are considered to be
Beckett’s propane conversion kits.
Use authorized replacement
parts only. Fuel orifices are
precision-machined parts and O-rings are rated for
fuel contact. Do not attempt to replicate or modify any
parts. Refer to Table 5 on Page 10.
With the propane orifice
installed, as shown in Figure
10 , Page 15, all burner air adjustments and
gas manifold pressure adjustments for propane
will be approximately the same as the natural gas
adjustments shown in the burner manual, or printed
on the “Mfr’s Settings” label on the burner housing.

Explosion, Fire and
Asphyxiation Hazard
This conversion kit must be installed
by a qualified service agency in
accordance with the manufacturer’s
instructions and all applicable codes
and requirements of the authority
having jurisdiction.
(In Canada, in accordance with the requirements
of the CAN/CGA-B149 Installation Code.) If the
information in these instructions is not followed
exactly, a fire, explosion, or production of carbon
monoxide may result causing property damage,
personal injury or loss of life. The qualified service
agency is responsible for the proper installation of
this kit. The installation is not proper and complete
until the operation of the converted appliance
is checked, as specified in the manufacturer’s
instructions supplied with the kit.
