This instruction manual provides operating
instructions, installation and service information
for the MiniMax NT Low NOx high performance
heater. The information in this manual applies to
the MiniMax NT Low NOx 200, 250, 300, and
400 natural gas models.
It is very important that the owner/installer read
and understand the section covering installation
instructions, and recognize the local and state codes
before installing the MiniMax NT Low NOx.
History and experience has shown that most heater
damage is caused by improper installation practices.
1. Spa or hot tub water temperatures should never
exceed 104° F. A temperature of 100° F. is
considered safe for a healthy adult. Special
caution is suggested for young children.
2. Drinking of alcoholic beverages before or during
spa or hot tub use can cause drowsiness which
could lead to unconsciousness and subsequently
result in drowning.
3. Pregnant women beware! Soaking in water
above 100° F. can cause fetal damage during the
first three months of pregnancy (resulting in the
birth of a brain-damaged or deformed child).
Pregnant women should stick to the 100° F.
maximum rule.
Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the
appliance. Do not use this heater if any part has been under water. Immediately call a qualified service
technician to inspect the heater and to replace any part of control system and gas control which has been
under water.

circulatory problems, diabetes or blood pressure
problems should obtain their physician's advice
before using spas or hot tubs.
