Where appliance instructions differ from this manual, follow the appliance instructions.
1. Prepare site • prepare burner • mount burner
(continued)
Verify and install diffuser plate
Each plate will be stamped on the face of the diffuser with a letter desig-
nating the diffuser type (Example A, B, C, 9S).
1. Install the diffuser on the air tube by placing the wide tab into the slot at
the end of the air tube with the 90° bent tabs of the diffuser plate facing
into the air tube.
2. Fasten diffuser plate to the air tube with the two screws provided.
3. Make sure the flame rod and electrode are not touching the diffuser
plate.
4. If flame rod or electrode is making contact with the diffuser plate the
burner will not prove flame and will enter a lockout condition
Flame rod and ignitor electrode
• Inspect the burner from air tube end. Flame rod should extend through
the diffuser plate as shown in Figure 4. Ignitor electrode should be
flush with inner face of diffuser plate as shown.
• Push rod completely forward.
Figure 4 Flame rod and ignitor placement
• The flame rod and ignitor electrode must not touch the diffuser or any
grounded metal surface at any point. The flame rod and electrode
should be as close as possible to the centers of the diffuser holes. If
either the flame rod or electrode is closer than 1/16" to the diffuser,
remove assembly (see page 15 for removal instructions and verify
dimensions per Figure 5). Bend the end of the flame rod or ignitor
electrode as required. Replace assembly and check spacing again.
Continue adjusting as necessary until neither flame rod nor electrode is
closer than 1/16" to the diffuser.
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 damage.
• Unplug wire harness from combination gas valve.
• Remove the combination gas valve (item 20, page 3) and the orifice
nipple (item 6, 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.
•
Ifgasorificeissmallerthanrequired,
redrill the orifice to the correct
size, if necessary.
•
Ifgasorificeislargerthanrequired,
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 (or on the French label
attached to the burner for Canadian installations).
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 all
gas piping connections per Figure 6. The orifice nipple is installed be-
tween the gas valve and the burner connection. Make sure the arrow
on the orifice nipple label points in the direction of gas flow.
To avoid damage to gas valve, do not hold valve with a
pipe wrench or over-tighten. Use only a crescent wrench
or other means. Failure to comply could result in severe
personal injury, death or substantial property damage.
3. Connect wire harness to valve.
LP gas conversion kit not required when installing LP
gas. Manifold gas pressure required for both natural
gas and LP is 3.5" WC unless specified.
Inspect components and wiring
• Visually inspect all burner components and wiring.
• Verify that wiring is intact and connectors are securely connected.
• Verify that all burner components are in good condition.
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
Flame Rod
Tip should extend in front of
diffuser by 1 1/4".
Ignitor Electrode
Tip should be flush with
inside surface of diffuser.
