Model 201GAS burner — Instruction manual
Carlin part number MN201GAS Rev. 03/14/11
– 8 –
Where appliance instructions differ from this manual, follow the appliance instructions.
Mount burner in appliance
• Verify appliance burner front plate dimensions per page 19.
• Slide gasket supplied with burner over end of air tube.
• Insert burner into appliance opening and bolt in place.
Inspect components and wiring
• Visually inspect all burner components and wiring.
• Verify that wiring is intact and leads are securely connected.
• Verify that all burner components are in good condition.
Install gas valve on burner
1. Read WARNING’s on page 9 before installing gas valve.
2. Apply a small amount of pipe dope (suitable for propane gas) to gas valve
outlet connection and to threads of gas line union and nipple. Assemble
pipe nipple to gas valve and one half of union. Assemble other half of union
to burner gas connection nipple. Join the union.
To avoid damage to gas valve, do not hold valve with a pipe
wrench or overtighten. Use only a crescent wrench or other
means. Failure to comply could result in severe personal injury,
death or substantial property damage.
3. Feed wires into air pressure switch housing and secure conduit fitting with
lock nut.
4. Connect white wire from valve to white wire from burner with wire nut.
Attach black wire quick-connect terminal to switch terminal connector
(violet wire from burner is attached to other switch terminal).

Inspect/redrill gas orifice when required
• Turn off power to the burner/appliance before proceeding.
• Close main manual gas valve in gas line to burner. Then disconnect the
ground joint union to allow rotating burner combination gas valve.
You must disconnect power to burner and close main manual
gas valve before proceeding. Failure to do so could result in
severe personal injury, death or substantial property dam-
age.
• Remove wire junction box cover on gas valve by removing the single
screw attaching the box to the valve body. Then pull the two insulated
spade connectors off of the gas valve terminals.
• Remove the combination gas valve (item 21, page 3) and the orifice
nipple (item 8, page 3). Remove the orifice nipple from the gas valve.
• Read the correct orifice drill size from Table 1, page 7. Then check
actual orifice size using that size twist drill bit.
• If gas orifice is smaller than required, redrill the orifice to the correct
size, if necessary.
• If gas orifice is larger than required, obtain a replacement orifice
nipple from Carlin. If necessary, drill the orifice hole in the replacement
orifice nipple to the correct size.
Drill the orifice carefully, avoiding drill wobble. Wobble will
cause the orifice to be over-sized. The orifice nipple should
be secured in a vise, if possible, to ensure it is steady during
the drilling process.
• Write the orifice size on the orifice nipple label.
• Replace the gas valve and piping, using only pipe dope listed for use
with liquefied petroleum gases. Make sure the arrow on the orifice
nipple label points in the direction of gas flow.
Flame rod and ignitor electrode
• Inspect the burner from air tube end. Flame rod should extend through
the diffuser plate as shown in Figure 5. Ignitor electrode should be flush
with inner face of diffuser plate as shown.
