2.5.5 MFC Set-Up Procedure (Natural Gas)
1. Remove screw from outlet test point and connect gauge.
2. Ensure mains supply to unit is switched off.
3. Remove protective caps from screws marked NO PR, 1 STEP ADJ and REG ADJ.
4. Ensure NO PR screw is turned fully clockwise.
5. Ensure 1 STEP ADJ screw is turned fully clockwise.
6. Switch I/O fan switch and thermostat OFF ('O').
7. Press and hold pilot button in fully while repeatedly pressing and releasing igniter button until pilot lights.
8. Continue to hold pilot button in fully for 20 seconds before release. Pilot should remain alight but if it goes out,
push OFF button in and wait for the 3 minute lockout to release before repeating from Step 7.
9. Push main burner button down.
10. Switch main electrical supply to unit on and check that red neon becomes lit.
11. Switch I/O fan switch on. Set thermostat to 200C.
12. Adjust REG ADJ screw to achieve gas pressure of 15mbar (6" w.g.). Clockwise rotation to increase pressure and
vice versa.
13. Turn 1 STEP ADJ screw anti-clockwise, no more than a quarter turn. If necessary, re-adjust REG ADJ screw to
restore gas pressure to 15mbar.
14. Extinguish burner by turning thermostat knob OFF.
15. Re-light burner by turning thermostat knob to FULL while observing pressure gauge. Pressure should initially be 5
mbar, pausing for a brief period at this pressure before rising to full pressure of 15 mbar.
16. If, when performing operation in Step 15, initial pressure does not register or is below 5 mbar, open 1 STEP ADJ
screw a further eighth-turn and if necessary re-adjust REG ADJ screw to restore gas pressure to 15 mbar. Repeat
from Step 14.
When satisfied that burner pressure is correct and the two-stage ignition pressure facility produces smooth burner
lighting, turn off main gas and electrical supplies. Remove pressure gauge, replace pressure test point screw and
replace protective caps.
2.5.6 MFC Set-Up Procedure (Propane Gas)
1. Remove screw from outlet pressure test point and connect gauge.
2. Ensure mains supply to unit is switched off.
3. Remove protective caps from screws marked NO PR and 1 STEP ADJ.
4. Ensure NO PR screw is turned fully anti-clockwise.
5. Ensure 1 STEP ADJ screw is turned fully clockwise.
6. Switch I/O fan switch and thermostat to OFF ('O').
7. Press and hold pilot button in fully while repeatedly pressing and releasing igniter button until pilot lights.
