THE OPTIMIZER 250 OUTDOOR WATER FURNACE
The Optimizer 250 outdoor (or indoor*) water furnace is safe and highly efficient, conveniently
installed outside your house to give you the comfort you desire all year round using the oldest and
most environmentally friendly fuel of all: WOOD. (* inside outdoor buildings such as barn, shop, shed etc.)
This unique system has a fire pot and a multiple pass heat exchanger which are totally immersed in a
water jacket that keeps its components from overheating and warping. The front door is insulated
and built of heavy gauge material to eliminate warping. The boiler tube style heat exchanger is
designed to extract useful heat from the exhaust flue which is virtually smoke free before they exit
through the insulated stainless steel chimney.
The water temperature is maintained at the desired level by means of Johnson automatic controls.
The heated water is pumped to the house and the other buildings by means of individual circulating
pumps through an individual underground loop for each building or application. Always use the best
insulated and water proof pipe.
The heating loop will provide the required amount of heat to your house or building, regardless of
your existing heating systems as described later on. You can also add a water-to-water heat
exchanger to your system to provide you with all your domestic hot water requirements to increase
your fuel savings considerably.
The Optimizer 250 Water Furnace is equipped with a fan for forced combustion air to modulate the
burning rate as required, and with safety instruments that would prevent the water from overheating
or boiling.
Please follow the instructions contained in this Manual to enjoy the comforts of heating with wood in
a safe manner.
LOCATION
The ideal location for the Optimizer Water Furnace should be:
1. Outside your residence for safety and lower insurance rates.
2. In a separate structure such as your garage, shop or shed.
3. Away from storage of wood, chemicals and other flammable materials.
4. No closer than 50 feet from existing residence and other buildings.
5. Downstream of prevailing winds relative to main residence.
6. On the side of pipe entry to residence.
7. Proper clearance distance to combustibles.
RECOMMENDATION
For extra safety, we recommend a hot water circulation loop that will dissipate at least 10% (ten
percent) of the estimated heat output of the water furnace in the event that circulation is reduced
because of electrical power failure. This loop should be such that it can only be made inoperative by
a deliberate manual action. The minimum pipe to be used should be 18mm (.75 inch) in diameter.
4
PLACEMENT
We recommend a concrete or cement (noncombustible) slab for placing the Optimizer Water
Furnace. The slab should be at least four (4) inches thick, sixty two (55) inches wide and sixty (70)
inches long with a well packed sub-base. The unit weighs 3030 pounds plus 1980 pounds of water.
CHIMNEY
We recommend the use of insulated stainless steel pipe as a stack to minimize creosote formation. A
six (6) inch pipe is used for the Optimizer 250. The stack should extend at least four (4) feet above
the building where the Boiler is located. Use a proper approved chimney for indoor installs.
CLEARANCES
The Outdoor (indoor) Water Furnace should be placed in a location where it can always get a
significant amount of fresh air. This is important for the water furnace to operate efficiently, and to
have good combustion.
The minimum installation clearances to combustible materials are:
Back & Sides: Forty eight(48) inches(122 cm)
Front & Sides: Forty-eight (48) inches(122 cm)
Top Eighteen (18) inches(46 cm)
Flue Pipe: Eighteen (18) inches(46 cm)
Note: Adequate space should also be left around the outdoor water furnace in addition to the
required clearances for servicing and maintenance.
PIPE TRENCH
Pre-insulated pipes such as Urecon Dual Pex Flex, properly sized for circulation requirements,
are recommended to convey the hot water from the outdoor water furnace to each building.
The piping should be laid in a flat trench eighteen (18) inches to thirty six (36) inches deep. If
high water table is encountered, the trench may be shallower, traffic permitting. It is to your
advantage to be down deeper at the boiler/furnace especially as it makes the bend easier.
Use water tight pipe insulation is recommended as all Styrofoam will absorb water to the point
it becomes very poor insulation. Only use in high dry well drained areas if using at all.
ALL PLUMBING MUST BE DONE ACCORDING TO APPLICABLE LOCAL CODES.
5
WATER FILL-UP
After installing the Optimizer Water Furnace in place and connecting to it the supply and
return pipe(s) to and from the various buildings to be heated, IN ACCORDANCE WITH
APPLICABLE LOCAL CODES, the heating installation is ready to be filled with water.
Before filling the Optimizer Water Furnace with water, make sure all valves are in “closed”
position, and unused supply and return outlets in the control panel of the outdoor water
furnace are tightly capped or valves installed for future use.
A permanent water supply to the Outdoor Water Furnace is recommended by tapping into the
water mains and connecting it to the top of the Outdoor Water Furnace through a manually
operated shut-off valve. Use only good quality water. Do not use water with iron, minerals, or
hard water. Do not use reverse osmosis water. Rain water is usually the best.
Add water until the entire heating installation is filled and the water level gauge on top of the
outdoor water furnace indicates almost full. (This will allow for water expansion.)
Before starting the outdoor water furnace make sure the entire heating installation is properly
vented to facilitate the circulation of water in the heating loop(s).
Ensure water trap and discharge pipe are properly installed and unobstructed to release any
pressure build-up in the outdoor water furnace.
CORROSION CONTROL
To control corrosion in the Portage & Main Outdoor Water Furnace we recommend the
following:
1. Always use certified boiler treatment. Submit water sample for testing annual through
your dealer. Keep your records.
2. Always maintain the proper water level.
3. Add a commercially available antifreeze solution to the water in the order of thirty (30)
per cent, during the initial water fill-up. Optional.
4. When adding large make-up water quantities to compensate for evaporation and to
maintain proper water level, use the same ratio of antifreeze solution to the make-up
water. For smaller make-up water quantities, no antifreeze solution is required.
5. If sedimentation occurs after the initial few weeks, the water should be treated
chemically to adjust its pH level. Consult your dealer for water analysis and treatment.
6. Keep ashes to minimal. Do not burn garbage.
ELECTRICAL CONNECTIONS
The Optimizer 250 Water Furnace is factory-wired and is ready for connecting it to an
AC/120V/60 Hertz supply
ALL ELECTRICAL CONNECTIONS SHOULD BE WIRED ACCORDING TO APPLICABLE LOCAL
CODES.
Make sure outdoor water furnace (and metallic water lines, if used) is well grounded to avoid
pitting in the water jacket.
6
STARTING-UP
Before starting-up observe the SAFETY WARNINGS contained in this Manual.
Make sure the Outdoor Water Furnace, circulating loops and existing heat exchangers or
baseboard heaters are full of water and properly vented.
Ensure the circulating pump(s) is properly installed according to manufacturer’s instructions.
Failure to do so could void the Warranty.
Load the outdoor water furnace with wood only to fill half of the firepot. Use kindling wood to
start the fire. DO NOT USE ANY FLAMMABLE LIQUIDS TO START THE FIRE.
Always turn the power off before loading the appliance with wood or opening the firing door.
Keep firing and gasification chamber doors tightly closed at all times for safety when outdoor
water furnace is in use. Always open doors slowly.
Inspect the chimney and make sure it is clear from any obstructions.
Set the aquastat to the highest temperature setting on the dial (180 F) as described under
SETTING. When the water temperature reaches this set point, the control will turn the
combustion fan off to close the air damper in the back of the outdoor water furnace.
When the combustion fan is shut off turn the setting dial down to a range of 160 to 180 F.
Now turn the circulating pump(s) on and leave it on at all times.
Before leaving the Outdoor Water Furnace location, make sure that:
1. The water level is adequate.
2. The wood loading door is tightly closed.
3. All doors are tightly closed.
4. The area around the outdoor water furnace is clear from any combustible materials.
SETTING
The Portage & Main Outdoor Water Furnace is equipped with a digital display immersion type
aquastat controller which operates in response to water temperature changes.
To set the temperature at the desired level, go to page 19 of this manual.

OPERATING INSTRUCTIONS
1. The Optimizer 250 Water Furnace may be connected to an existing boiler system. Burn natural
wood only. Make sure the wood is dry and split if required to dry. Cover wood to protect from
fall rains and snow.
2. To avoid damage load wood carefully. Always shut off power before opening firing door or
loading the appliance with wood. Unlatch the firing door to the first catch, allow 5 seconds for
smoke to dissipate before opening door fully. There is also a switch for the blower fan in the
front of the furnace which should be turned off before opening the firepot door.
3. Do not use chemical substances or liquid fuels to start or enhance the fire.
4. Do not burn garbage, liquid fuels, engine oil, naphtha or other flammable materials, which
may cause a fire or an explosion or cause corrosion.
5. The Optimizer 250 has 2 air flow adjusting valves located in the back of the unit inside the
control panel. The air box where the blower fan is mounted on has two handles on it, the top
one is the primary air which supplies air to the firebox, the bottom one is the secondary air
with supplies air to the exhaust after it leaves the fire box these two valves need to be
adjusted accurately so that the gasifying process is correct.
6. To adjust the air flow it seems that the top valve (primary air) can be open 4 to 5 turns, and
the bottom (secondary air) is only 3 to 4 turns. To insure a good setting you can look at the
flame coming out of the fire pot into the reaction chamber, at max burn you should see a very
intense flame like a blow torch exiting the fire pot.( For this process to work efficiently the
wood has to be dry and of smaller diameter (3 to 4 inches). Experience will show you the
best size of wood. Smaller dry wood help build up a coal bed.
7. Clean the heat exchanger regularly to remove accumulated ash. Flue pipe and chimney need
to be cleaned periodically.
8. Clean the Outdoor Water Furnace and cap the chimney at the end of each heating season to
minimize corrosion during summer months.
9. Always maintain the Outdoor Water Furnace, flue pipe and chimney in good condition.
10. Do not load the Outdoor Water Furnace with wood during an electrical power failure. Do not
leave fire door open.
11. For safety do not store any fuel or combustible materials within the installation clearances of
the outdoor water furnace.
12. Keep firing, gasification and heat exchanger doors tightly closed at all times for safety.
13. Always keep 4 to 5 inches of ash (hot coals) in the fire box; the furnace works best when this
ash bed is kept. Keep the ash area below the firepot in the reaction chamber clean and free
from ash to allow maximum air to exit the firepot.
SAVING TIPS
Keep the circulating pump(s) on all the time to maintain a comfortable environment and avoid
temperature swings and settling of suspended matter in the water. For summer the pumps
may be left running to minimize pump seizure or they may be generally turn off and
occasionally turned on.
Maintain a regular wood-loading schedule to keep the Outdoor Water Furnace operating under
steady-state conditions
Turn the circulating pump(s) on occasionally during summer to minimize pump seizure.
8
CORROSION CONTROL
To control corrosion of the Outdoor Water Furnace, we recommend the following:
1. Use proper certified boiler treatment as recommended by the furnace manufacturer.
2. Use antifreeze as described under Water Fill-Up.
3. Always maintain adequate water level. If level drops occasionally, check for leaks or boiling of
boiling water and refer to the Troubleshooting Section.
4. Make sure the Outdoor Water Furnace is properly grounded.
5. Remove ashes when Outdoor Water Furnace is not used.
6. Cover the chimney during off-season to prevent rainwater from entering the firepot.
7. Clean the firepot during the off-season.
8. Clean the heat exchanger with the cleaning tool provided with the Outdoor Water Furnace,
through the cleaning door located above the wood-loading door.
CREOSOTE CONTROL
The Optimizer when operated properly will have little or no creosote in the heat exchanger
tubes, all that should accumulate there is very light ash or dust. If creosote does form in the
heat exchanger tubes then the gasification process is not working properly.
Accumulations of creosote when ignited may result in chimney fires.
We recommend inspecting the chimney once a month during the heating season and removal
of creosote linings to reduce chimney fire hazards.
Green or unseasoned wet wood or wood that is not covered with a roof will likely be higher
that 25% moisture. This wood will cause creosote to form.
Leaky door gaskets will also cause creosote to build up.
ASH DISPOSAL
Ashes should be removed from the Outdoor Water Furnace regularly or they will block the flow
of air exiting the fire box.
Ashes should be stored in metal containers with tight lids and kept in an area free of
combustible materials until finally disposed.
Do not dispose of ashes while embers are still hot.
Check local by-laws for ash disposal. Wood ash can be used to reduce soil acidity or as a
fertilizer for the garden.
SAFETY WARNINGS
Never leave children un-attended near the outdoor water furnace/boiler.
Never add water when outdoor water furnace temperature is close to 212 f as it
may result in steam flashing.
Never perform any service or maintenance work before water temperature drops
below 100 F.
DO NOT store combustible materials or liquids near the Outdoor Water Furnace.
DO NOT burn any materials other than natural wood.
DO NOT use flammable liquids or materials to start or to enhance the fire.
DO NOT leave wood loading door open or unlatched.
9
DO NOT open the loading door too quickly to avoid blowbacks which could cause severe
burns.
ALWAYS check water level, aquastat and damper setting for a proper and safe operation.
Lock doors with your own locks as required.
Never allow unauthorized opening, filling or servicing of the furnace
DO NOT touch any part on the front of the Outdoor Water Furnace, which are not insinuated
to avoid skin burns.
ALWAYS store ashes in tightly covered metal containers away from combustible materials.
It is not designed to be used as an incinerator.
MAINTENANCE
Optimizer 250 Outdoor Water Furnace is designed to operate for many years with the least
amount of maintenance. Good housekeeping practices and observance of the instructions
contained in this Manual would assist you in maintaining the outdoor water furnace in good
and safe working conditions.
ALWAYS SHUT OFF THE POWER SUPPLY prior to performing any service or maintenance work.
Refer to the SAETY WARNINGS and OPERATING INSTRUCTIONS prior to performing any or
maintenance work.
If circulating pump(s) is seized due to a prolonged shutdown, removed the screw in the center
of the motor and turn the motor shaft with a screwdriver to loosen it.
The Primary and secondary air have to be manually adjusted to the desired amount of air required.
This is done simply by turning the handles (as previously described on pages 8 and 9) on the primary
and secondary air flow adjuster. This blower fan assembly should not be altered in any way for
increased fire.

CONNECTION TO HEATING SYSTEMS
The P & M Heating System is versatile and can be connected to any existing or new heating system
and/or domestic water system as described below. The corresponding schematics are provided
as a guideline only. ALL CONNECTINS MUST BE EXECUTED ACCORDING TO LOCAL PLUMBING
AND ELECTRICAL CODES.
1. EXISTING FORCED AIR SYSTEM
All you need is to install a water-to-air heat exchanger in your existing furnace plenum (on the
supply side) to keep your house as comfortable as you desire using a separate thermostat.
Your existing furnace would be used as a back up when required. (Refer to Schematic #1)
2. EXISTING WATER BASEBOARD SYSTEM
A water-to-water heat exchanger will be required to replace your existing boiler and provide
you with all the comfort you require. Your existing boiler would be used as a back up when
required. (Refer to Schematic #2). Another alternative would be to convert your existing
system into an “open system” with the assistance of an expert in heating system.
3. DOMESTIC WATER HEATER AND HEATING SYSTEM
You can enjoy more energy savings and running hot water during the heating season by
connecting your domestic water heater to the Portage & Main Heating System through a
sidearm water heater. (Refer to Schematic #4). We would caution you, however, that creosote
may increase during summer due to lowered heat demand. But if additional heat could be
used elsewhere, then creosote formation would be reduced.
4. HOT TUB, POOL HEATING use shell tube and shell heat exchanger.

The A419 control functions
Set point (SP) establishes the temperature value at which the equipment is switched on or off,
depending on the user selected mode of operation. Set point range is -30 to 212˚F or -34 to 100˚C
(in 1-degree increments).
If Set point mode is set to cut-in, set point is the temperature value at which the control closes the
Normally Open (N.O.) contacts. If Set point mode is set to cutout, set point is the temperature at which
the N.O. contacts open.
Differential (DIF) established the difference in temperature between the cut-in value and cutout
value. The differential is set relative to Set point and may be set from 1 to 30 F˚ or -17 to -1 C˚ (in 1 –
degree increments).
Anti-Short Cycle Delay (ASD) established the minimum time that the outplay relay remains deenergized before the next on-cycle. The ASD does not allow the output relay to re-energize until the
programmed time delay has elapsed. The delay is activated when the control is first turned on and
every time an on-cycle ends. When the delay is activated, the LCD alternately flashed the senor
temperature and ASD. The anti-short Cycle Delay range is 0 to 12 minutes (in 1-minute increments).
Sensor Failure Operation (SF) establishes how the A419 control’s output-relay operates the
equipment in the event of a sensor or sensor wiring failure. The user may select to run the equipment
continuously or to shut it down. When the control detects a sensor circuit failure, the LCD flashes SF
alternately with OP (if the sensor circuit is open), or SH (If the sensor circuit is shorted). Before
indicating a failure, the control implements a 1-minute delay, which allows verification of failure
condition and avoids nuisance failure indications.
Temperature Offset (OFS) establishes a set secondary Set point and Differential values that may
be invoked to control an application when a circuit is closed between the binary input (BIN) and
common (COM) terminals (and BIN appears on the display). See Figure 3. Offset range is 0 to 50F˚ or
C˚ (in 1-degree increments). A typical application might use a switching time clock to invoke nightsetback temperature settings.
IMPORTANT: Make sure the Touchpad Lock jumper is installed (unlocked) before attempting to
adjust the A419 control functions.
