ASSEMBLING THE STACK ASSEMBLY
Poorly fitted stack sections may allow hot stack to fall on shelter and start a fire, or deadly
carbon monoxide to leak into shelter. Ensure sections seat together securely.
During operation, the SHS produces harmful carbon monoxide (CO) and other gases.
Carbon monoxide is a colorless, odorless, and tasteless gas. Mild cases of carbon
monoxide poisoning can cause symptoms such as nausea, dizziness or headaches.
Severe cases of carbon monoxide poisoning can result in brain damage, heart damage
or death. Remember that although CO has no telltale odor, it may mix with other odors
which mask its presence; therefore, CO can be present within a mix of seemingly
To prevent CO poisoning, ensure that the SHS exhaust stack sections fit together snugly
and that the exhaust gases are properly vented through the roof of the shelter.
The best way to prevent CO poisoning is to keep the SHS in good working order. Ensure
that all possible sources of CO leakage have been repaired and that the operating space
is well ventilated.
Before the heater can be used, the stack must be assembled outside the shelter, installed in the heater
stack adapter and stabilized with the provided guy lines.
The stack assembly is provided as six separate stack sections nested inside one another. Disassemble
the individual sections of the stack assembly (1) and organize them by number on the ground. Take note
that the number (2) of each stack section is stamped into the side of the section.
