6.6 Operating the Burner and Set-Up
6.6.1 Set-Up for 0 to 2500 Feet Altitude
The setup must be checked before the unit is put
in operation. Problems such as failure to start, rough
ignition, strong exhaust odors, etc. can be due to
improper setup. Damage to the Brute Deluxe resulting
from improper setup is not covered by the limited
warranty.
1. Using this manual, make sure the installation
is complete and fully in compliance with the
instructions.
2. Determine that the appliance and system are
lled with water and all air has been bled from
both. Open all valves.
3. Observe all warnings on the Operating
Instructions label and turn on gas and electrical
power to appliance.
4. Switch on the appliance power switch located on
the right side of the unit.
5. The Brute Deluxe will enter the start sequence,
as long as the unit is being called for heat. The
blower and pump come on for pre-purge, then
the ignitor warm-up sequence starts and after
the ignitor warm-up is complete and all safety
devices are veried, the gas valves open. If
ignition doesn’t occur, check that there is proper
gas supply. Wait 5 minutes and start the unit
again. During initial start up, air in the gas line
may cause the Brute Deluxe to "lock out" during
the rst few trials for ignition. If the ignition
control locks out, reset by cycling the power off
and on using the main power switch on the right
side of the cabinet.
6. When the unit is running, the supply gas pressure
must be checked. Inlet gas pressure must not
exceed 13 in. w.c. (3.2 kPa). The minimum inlet
gas pressure is 5 in. w.c. (1.2 kPa) and 8 in. w.c.
(2 kPa) for LP.
7. Once the inlet gas pressure is veried, the
outlet gas pressure from each valve (manifold
gas pressure) must be checked, and adjusted, if
necessary. The manifold gas pressure must be 3.0
in. w.c. (0.62 kPa) for natural gas and 9.0 in. w.c.
(2.2 kPa) for LP.
8. Complete the setup by checking the CO
2
at the
outlet of the unit. The CO
2
should be 8% for
natural gas, or 9.2% for LP.
9. After placing the appliance in operation, the
Burner Safety Shutoff Device must be tested.
To test:
(a) Close gas shutoff valve with burner
operating.
(b) The ame will go out and blower will
continue to run for the post purge cycle.
Three attempts to light will follow. Ignition
will not occur as the gas is off. The ignition
control will lockout, and will have to be
reset by cycling the power before the unit
will operate.
(c) Open gas shutoff valve. Restart the
appliance. The ignition sequence will
start again and the burner will start. The
appliance will return to its previous mode
of operation.
6.6.2 High Altitude Adjustment and
Set-Up
High altitude adjustment must not be made on
appliances operating at elevations below 2500 ft. (762 m).
No orice changes are required to adjust the
Brute Deluxe appliances for high altitude. High
altitude adjustment is accomplished by adjustment
of the air shutter. A CO
2
or O
2
analyzer is required to
make these adjustments.
Start the adjustment process by checking the CO
2
in the “as installed” condition. Adjust the air shutter(s)
so that the CO
2
is about 8% or the O
2
is about 6.8%
for appliances operating on natural gas. For appliances
operating on LP Gas adjust the air shutter(s) so that the
CO
2
is about 9.2% or the O
2
is about 6.8%.
If the appropriate CO
2
/ O
2
levels cannot be
achieved by adjusting the air shutter. Contact the
Technical Services Department at number shown on
back page.
The amount of derate will vary depending on
heating value of the fuel and the elevation at the
installation site.
Caution
Should any odor of gas be detected, or if the gas
burner does not appear to be functioning in a
normal manner, close main shutoff valve, do not
shut off switch, and contact your heating contractor,
gas company, or factory representative.
Attention
Si vous sentez une odeur de gaz ou si le brûleur
à gaz ne parait pas fonctionner de manière
normale, fermez la vanne d’isolement, ne fermez
aucun interrupteur, et appelez votre entreprise de
chauffage, la compagnie de gaz ou un représentant
du fabricant..
6.7 Shutting Down the Brute Deluxe
1. Switch off the main electrical disconnect switch.
2. Close all manual gas valves.
3. If freezing is anticipated, drain the Brute Deluxe
and be sure to also protect building piping from
freezing.
This step to be performed by a qualied
service person.
