Indicates a potentially hazardous situation
which, if ignored, can result in serious injury
or substantial property damage.
Indicates special instructions on installation,
operation or maintenance, which are impor-
tant to equipment but not related to personal
injury hazards.
NOTICE
WARNING
Failure to follow instructions below can result in
severe personal injury or damage if ignored:
- Instructions are for a qualified installer /
service technician
- Read all instructions before proceeding
- Follow instructions in the proper order.
For your safety, turn off electrical power sup-
ply at service panel and allow unit to cool be-
fore proceeding. Failure to do so can cause
severe personal injury or death.
Upon completion of the conversion from Nat-
ural to ropane, affix the new rating label in-
cluded in the kit to the unit adjacent to the
existing rating label. DO NOT affix the new
label over the existing rating label. Add
propane conversion labeling to the gas valve.
These instructions cover Natural to ropane
conversion for MCBA and TriMax controlled
restige boilers. Specific control related in-
structions are denoted as (MCBA) or (TRI-
MAX).

Installation of the Natural Gas Orifice
1. Turn off the electrical power supply to the boiler.
2. Close the external manual gas shut off valve to the
unit.
3. Remove the front panel of the Prestige by remov-
ing the thumb screw along the upper edge of the
unit. Lift the panel up and pull forward to remove
the front panel from the unit.
4. Remove the Phillips head retaining screw at the
bottom of the control panel assembly. Swing
open the control panel assembly ( CBA).
5. Slide control panel retaining clips inward and
swing control panel down (TRI AX).
6. Remove the air inlet elbow from the venturi using
a twist motion.
7. Disconnect the gas supply piping inside the Pres-
tige at the union located below the gas valve. See
Fig. 1.
8. Disconnect the wiring from the gas valve.
9. Remove the six T-40 Torx screws securing the
venturi to the blower. See Fig. 2.
10. Remove the gas valve/venturi assembly from the unit.
11. Remove the (4) T-25 Torx screws securing the gas
valve extension pipe to the venturi. See Figs. 1 & 2.
12. Remove the existing propane gas orifice from between
the gas valve extension pipe and venturi.
There are O-ring gaskets between the venturi and
blower housing and also between the venturi and
gas valve extension pipe. These O-Rings must be
reinstalled with the gas valve/venturi assembly.
Use care not to damage these gaskets.

13. Install the brass natural gas orifice and o-ring gas-
kets between the gas valve extension pipe and the
venturi. Ensure that the orifice and gaskets are in-
side the retaining ring cast into the venturi.
Taper on gas orifice should face the gas valve ex-
tension pipe. See Figs. 1 & 2.
Table 1: ropane Gas Orifice
Failure to retain the O-ring gaskets between venturi
and gas valve extension pipe will cause an improper
seal resulting in a potential risk of a gas leak. Any
potential gas leakage may result in death, serious
injury or substantial property damage.
14. Reassemble the gas valve extension pipe onto the
venturi using the four T-25 Torx head screws. En-
sure that the gas valve extension pipe is properly
oriented with the venturi.
There is a gasket between the venturi and the
blower housing. This gasket must be reinstalled.
Use care not to damage the gasket.
15. With the venturi / blower O-ring in place, re-
assemble the venturi / gas valve assembly to the
blower housing using the six T-40 Torx screws.
For the reassembly process do not use adhesive on
the venturi / blower gasket.
Use care in the reassembly of the venturi / gas
valve to the blower housing not to cross thread the
mounting screws. Support the weight of the ven-
turi / gas valve assembly when threading the
mounting screws.
16. Reconnect the wiring to the gas valve as shown
in Fig. 3.
17. Reconnect and tighten the internal gas supply
union using two wrenches and open the external
manual gas shut off valve. Before placing the
Prestige boiler back into operation check and test
all gas connections for leaks. Repair leaks if
found.
Do not check for gas leaks with an open flame.
Use a bubble test. Failure to check for gas leaks
can cause severe personal injury, death or substan-
tial property damage.

There are O-ring gaskets between the air intake
elbow and the venturi air intake. These gaskets
must be installed with the air intake elbow. Use
care not to damage the gasket.
18. With the air intake elbow O-rings in place, re-
assemble the air inlet elbow to the venturi.
19. Reposition the control panel and reattach the re-
taining screw ( CBA).
20. Swing control panel up to engage retaining clips
(TRI AX).
21. Replace the front jacket panel and secure with the
thumb screw along the upper edge.
22. Turn on the electrical power supply to the Prestige
boiler and return the unit back to service.
Combustion Test and Adjustments
1. The installer UST perform a complete combus-
tion check to ensure the following combustion lev-
els are met at high and low input firing rates and
the burner is operating at optimum conditions.
Table 2: Recommended Combustion Settings
The combustion testing and adjustments must be
performed by a qualified installer, service agency
or the gas supplier. All combustion measurements
must be performed with calibrated equipment to
ensure proper readings and accuracy.
Failure to perform a complete combustion test at
both high and low input rates may result in incom-
plete combustion and the production of carbon
monoxide, which can cause severe personal injury,
death or substantial property damage.
MCBA Instructions (MCBA)
1. anually place the boiler into high fire mode by
pressing the “ ODE” button with “+” button si-
multaneously on the control panel display while
in the Standby (STBY) mode.
The control panel will display a H followed by the
current boiler temperature when placed into high
fire test mode.

2. If the combustion levels during high fire is outside
the recommended combustion settings in Table 2,
adjust the THROTTLE SCREW (see Fig. 3)
using a flat-blade screwdriver.
The throttle screw is highly sensitive and requires
the use of a combustion analyzer for adjustment.
An adjustment as small as an 1/8 of a turn can pro-
duce a large change in combustion levels.
3. Once the combustion level is set at high fire, man-
ually place the boiler into low fire mode by press-
ing the “ ODE” button with “-” button
simultaneously on the control display while in the
Standby (STBY) mode.
The control panel will display a L followed by the
current boiler temperature when placed into low
fire test mode.
4. If the combustion levels (O2or CO2) during low
fire is not within +/- 0.2 of the combustion level
measured at high fire, remove the offset cover
screw and adjust the plastic OFFSET SCREW
(see Fig 3) using a T-40 Torx wrench as follows:
Counter-clockwise adjustment of the OFFSET
SCREW at Low Fire:
O2 increases and CO2 decreases
Clockwise adjustment of the OFFSET SCREW at
Low Fire:
O2 decreases and CO2 increases
5. Press the “+” and “-” buttons simultaneously to
shutdown the burner.
Trimax Control rocedure (TRIMAX)
1. Press the round INSTALLER button. See Fig. 4.
2. Enter the installer access code “054” by using the
LEFT and RIGHT buttons to select a digit and
the U and DOWN buttons to change the digit.
Press the OK button to enter the access code.
3. Press the RIGHT button to highlight the anual
Operation icon then press the OK button.
4. Press the OK button while the FAN icon is high-
lighted to manually fire the burner and power the
CH circulator.
An adequate CH load must be present to dissipate
the heat generated during the combustion test. If
an adequate CH load is not available, an indirect
water heater can be used to dissipate the heat by

5. Press the RIGHT button to adjust the firing rate
to 100% (high fire). Hold down the RIGHT but-
ton to rapidly increase the firing rate.
6. If the combustion levels during high fire are out-
side the recommended combustion settings in
Table 2, adjust the THROTTLE SCREW (see Fig.
3) using a flat-blade screwdriver.

duce a large change in combustion levels.
7. Once the combustion level is set at high fire, man-
ually place the boiler into low fire mode by press-
ing the LEFT button to adjust firing rate down to
0% (low fire).
8. If the combustion level (O2or CO2) during low
fire is not within +/-0.2 of the combustion level
measured at high fire, remove the offset cover
screw and adjust the plastic OFFSET SCREW
(see Fig. 3) using a T-40 Torx wrench as follows:
Counter-clockwise adjustment of OFFSET
SCREW at Low Fire (0% firing rate):
O2increases and CO2decreases
