1. Select exhaust makeup air fan air flow rate
(cfm or l/s) to be equal to or exceed the
maximum airflow rate of the compensation
for exhaust system. The airflow rate
indicated for each fan model includes
anticipated static pressure losses for all
makeup air system components and an
allowance for up to 50 equivalent feet
(15 m eq.) of 12” (300 mm) round ductwork.
2. If makeup air tempering is required,
identify the Zone from map and select the
heater for your Zone. The Selection table
suggests heater capacity based on winter
outdoor temperature.
3. Select the remaining system components
under the appropriate column for the fan
and heater selected in previous steps.
Quantities of more than one are indicated
in parentheses (). If the optional silencer
is included, increase and/or decrease
the fast clamp quantities as indicated in
parantheses ().
