DANGER
Asphyxiation Hazard. Failure to properly convert this boiler for use on LP gas can cause unreliable
operation at elevated carbon monoxide (CO) levels, resulting in personal injury or death.
NOTICE
To minimize the risk of premature heat exchanger failure, observe the following water chemistry requirements:
1. Minimize the introduction of make-up water, dissolved oxygen, and contaminants into the boiler by following
the installation guidelines shown in the “Water Quality and Boiler Water Additives Note” on Page 70.
2. Make sure the system is filled with water meeting the following criteria:
• pH between 6.5 and 9.5 (for systems containing aluminum components, between 6.5 and 8.5)
• Chloride level less than 200 PPM. If fill water is drawn from a system containing a water softener, test a
sample of the fill water to confirm that this criteria is met.
• Hardness less than 7 grains/gallon.
3. Avoid the use of petroleum based boiler additives and ester-based oils/lubricants.
These can attack seals in both the boiler and system.
4. If freeze protection is required, use the following or its equivalent:
• Fernox Alphi -11 (inhibited Propylene Glycol)
• Sentinel
®
X500 Inhibited Propylene Glycol antifreeze (combined antifreeze and inhibitor)
Refer to the antifreeze manufacturer’s instructions for required dosage. In general these products are a blend
of glycol (for freeze protection) and inhibitors (to protect the glycol from attacking metallic system
components). Do not add any more antifreeze than is necessary to protect the system from freeze damage.
Many of these products require annual testing of the system water to ensure that the inhibitors are still active;
consult the manufacturer’s instructions for maintenance requirements. Allowance must be made for the
additional expansion of the glycol solution.
5. Test antifreeze and inhibitor concentration annually.
• Inhibitor concentration test kit for Fernox Protector F1, 25 tests per kit. Part Number: 101148-01
• Inhibitor, Fernox Protector F1, 1 pint (500 mL). Part Number: 101147-01
6. For system cleaning, use the following or its equivalent:
• Fernox Cleaner F3
• Sentinel
®
X300 System cleaner (for New Heating systems)
•
Sentinel
®
X 400 System Restorer (For old Closed Loop Hydronic Heating Systems)
Refer to the instructions supplied with the cleaner for proper dosage and use.

WARNING
Poison Hazard. Use only inhibited propylene glycol solutions specifically formulated for hydronic systems.
Do not use ethylene glycol, which is toxic and can attack gaskets and seals used in hydronic systems. Use
of ethylene glycol could result in property damage, personal injury or death.
