WATER TREATMENT AND TESTING
WATER TREATMENT AND TESTING
Water Treatment Policy
Water Treatment Policy
To qualify for warranty water must be tested a minimum of once per year and water treatment
added when necessary.
To test the water open the boiler drain located at the bottom of the rear of the furnace until the water
runs clear. Fill one of the test bottles provided to you by your dealer and mail to our testing lab using
the mailing carton and label provided with the bottle. Make sure to note if the furnace water contains
any antifreeze or additional chemicals. If any adjustments need to be made to the water you will
receive a report outlining what must be done. Take another sample and mail it to our test lab again to
verify the recommended changes have been made.
Add the water treatment through the fill pipe located at the top of the furnace when initially filling the
furnace with water or after testing, if needed. Ensure that all drains are closed. It is recommended
that water treatment be added at a 1:200 ratio when initially firing the furnace and 1:300 after that.
Additional treatment may have to be added for water with more severe properties or for systems with
more chemically demanding requirements. Recommended operating pH level is 9 – 10. 5.
Recommended nitrite levels are 600-1000 ppm.
What Water Treatment Does
What Water Treatment Does
The water treatment used in outdoor furnaces are nitrate based water treatments which act as
oxygen scavengers, neutralize harmful bacteria and harmful minerals and elements in your water to
reduce scaling and corrosion in your furnace and plumbing system.
Test Parameters and What They Mean
Test Parameters and What They Mean
Conductivity
Conductivity is a measurement of minerals in your furnace water. While it is common to have
minerals in water, in excess minerals can cause many problems in hydronic systems including scaling
and corrosion.
pH
pH is measurement of alkalinity (hard or soft water). For outdoor furnace water and the water
treatment used in outdoor furnaces it is better to have your water a little harder than softer
(recommended pH range is 9-10.5) as the active ingredients in the water treatment neutralize harder
water easier than softer water
Nitrates
Nitrates tested for are a measurement of how much water treatment is in the water. Nitrates
measured are active units of water treatment available to neutralize harmful elements in your furnace
water. Nitrates also act to neutralize harmful bacteria that may build up in the furnace water over
time.
Glycol
Inhibited glycol provides anti-corrosion elements and freeze protection for outdoor furnaces and is
compatible with Outdoor Furnace Water Treatment. Because outdoor furnaces are open to the
atmosphere systems and will have fresh water added occasionally, oxygen is always entering the
system and will break down the glycol over time to create glycolic acid which will harm your furnace
system. When this happens you will be required to drain and flush your furnace system.
It is always suggested to use 100% virgin glycol instead of recycled glycol as it will break down

For Outdoor Installation Only.
ATTENTION
offices
ATTENTION
SS furnace. Carefully read and follow these directions.
ATTENTION: Do not remove labels from furnace except in the case of servicing.
DANGER: Do not start fire with or burn chemicals, volatile fluids, rubber, plastics or garbage. Only
competent persons with a sound understanding of this heating method should operate this furnace.

- Do not store fuel or other combustible material within marked installation clearances
- Inspect and clean flues and chimney regularly
- Do not operate with flue draft exceeding 0.05-0.1”W.C in water column
- Maximum draft marked on nameplate
CAUTION:: Use of an approved spark arrester is recommended. It is the recommendation of
SteelTech Inc that a 30’ minimum distance of clearance from buildings and other combustibles. Your
local authorities and your insurance company may require a greater distance.
RECOMMENDED:: Choose the location of your furnace with concerns of wind direction, smoke odor,
sparks, blocked viewing and wood storage carefully. Be a responsible and considerate owner.
WARNING:: All installations and operations of your HEATMASTER SS product must follow STATE,
PROVINCIAL, and LOCAL LAWS pertaining to operations, wiring, plumbing and building codes.
CAUTION:: Check for buried cables and utility lines before digging the trench to your furnace.
WARNING:: All models operate at atmospheric pressure. DO NOT obstruct, block or plug the
overflow vent tube in any way which is located on top of the boiler either in front of or behind the
chimney.
CAUTION
- Keep children away.
- Do not touch during operation.
CAUTION
until heating fluid comes out of vent pipe on the top of the furnace.
WARNING:: Do not start a fire in the furnace without first filling with water. It will cause serious
damage to the furnace.
WARNING: :

Chimney
The chimney on your HeatMaster SS outdoor furnace is a stainless steel double wall insulated
chimney. It is attached to the furnace with a stainless steel adapter. The draft on the chimney is
typically 0.05-0.1”W.C.. To install chimney extensions be sure to purchase the same chimney as on
your furnace (Selkirk Ultra Temp). These chimneys are a twist lock connect chimney. Be sure to use
the chimney fastening ring to fasten the connection tight. Braces, elbow kits and roof flashing kits are
available through your dealer. It is not recommended that the chimney be longer than 15ft.
The chimney and flue pipe need to be kept clean and in good condition. See below for chimney
sizes.
MF-3000 - 6” Stainless Steel Double Wall Chimney and Adapter
MF-5,000 and MF-5000e– 6” Stainless Steel Double Wall Chimney and Adapter
MF-10,000e – 8” Stainless Steel Double Wall Chimney and Adapter
MF-20,000e – 10” Stainless Steel Double Wall Chimney and Adapter
NOTE: Chimney extensions and caps are useful for lifting exhaust gases and smoke away from
buildings. However, when burning a MF-5000e, MF-10000e or MF-20000e keep in mind that the
cooler exhaust temperatures as a result of the high efficiency burn of these furnaces may cause
excess creosote build up when chimney extensions and caps are used. This can lead to improper
burning and creosote build up in the furnace.
FURNACE INSTALLATION GUIDE
FURNACE INSTALLATION GUIDE
Installation should be performed by a qualified technician.
LOCATION
LOCATION
Maintain adequate clearance of buildings and combustibles. They are 0 inches from the sides of the
furnaces and 3 feet from the front and back. Pile and store wood outdoors under cover. Do not place
or store wood within stove installation clearances or within the space required for charging and ash
removal. Contact all governing authorities in your area prior to installation.
When choosing the location of your furnace you should consider prevailing wind direction, distance
from home for refueling and wood storage and give consideration for any effect on your neighbors.
FURNACE FOUNDATION
FURNACE FOUNDATION
Inspect the ground conditions that you intend to install your furnace on. If the area is unstable or has
a history of staying wet you may have to improve the soil with gravel as well as raise the level of
furnace placement. A cement pad of 4-6” in thickness should be used. The furnace in most cases
can be placed on 4 cement blocks not less than 6” wide X 10” long and 3” thick. The furnace should
never be installed on a combustible floor.
Find the footprint of the furnace you have purchased in the Appendix of this manual and place
your blocks so the legs will stand on the center of the blocks. Cement pads should be a little bigger
than the actual furnace, with about a 4’ extra length front and back so you have a solid working area.
