Model 99FRD, 100CRD & 102CRD oil burners — Instruction manual
Carlin part number MN99102 Rev. 08/20/08
– 18 –
Wire burner — 50200 primary control
1. All wiring must comply with:
• In the U.S — the National Electrical Code, ANSI Z223.1/NFPA 54.
• In Canada — the Canadian Electrical Code Part 1, CSA standard C22.1.
• All applicable local codes/standards.
2. Wire the burner following Figure 18 and any special instructions or wiring
diagram provided with the appliance, burner or other components.
3. The burner requires a 120 VAC/60 hz/single-phase power supply, with at least
a 5-amp fuse. The current draw (equipped with Carlin PSC motor) will be ap-
proximately 2.5 amps.
4. The 50200 thermostat terminals provide a power source. Never apply external
power to these terminals under any circumstances. To avoid this problem when
using zone valves, disconnect field wires from 50200 thermostat terminals. Then
connect a voltmeter across terminals. Operate all zones and verify that there
is never a voltage reading at the meter. A voltage reading indicates incorrect
wiring that must be corrected before attempting to operate the burner.
5. Alarm terminals provide a 24 vac-rated dry contact, suitable for use with security/
fire alarm systems such as Carlin SecureHeat™.
6. Make sure the burner and appliance are correctly wired and the line switch is
properly fused for the load.
To start burner
Do not start the burner if the combustion chamber contains
oil or oil vapor.
1. Turn service switch OFF.
2. Perform inspections and checkouts on pages 18 and 19.
3. Slip one end of a 3/16-inch I.D. clear plastic hose over end of bleed valve, the
other end into a container. Then open bleed valve.
4. Set thermostat (operating controls) to call for heat.
5. Turn service switch ON.
6. Bleed oil line until plastic line is free of bubbles; then another 15 seconds longer.
(Should the primary control timing cause a lockout during purging, restart the
burner following the primary control data sheet instructions.)
7. Close bleed valve. The burner should cycle through the sequence given in the
primary control data sheet.
8. Perform primary control flame failure lockout and safety timing tests per instruc-
tions in primary control data sheet.
9. Should control/burner fail to operate correctly, see page 19 for suggestions in
troubleshooting.
4. Wire burner • start burner — 50200 primary control
