Tips & Warnings
This type of heater system may not be recommended for really cold climates. Fresh air brought in at extremely cold temperatures can be expensive and difficult to heat up.
Failure to have adequate fresh air can result in suffocation. Read your individual heater's manual to see how much fresh air is required to operate.
