2. Determine where the support(s) will be located between the guides.
a. Single Support - locate at the center of the unit.
b. Two Supports – locate from jamb (DBG/2)
c. Three Supports
i. Locate each end from guide face at (DBG/3) – 1 5/16”
ii. Locate middle support at center of unit
3. Single section hoods will require a hood support on BJ units that have a DBG greater than 6 feet.
a. Use only the fascia side of the hood support in this case.
4. Mark a line on the lintel at the centerline of each support.
5. Check the construction at the support locations to be sure it is strong enough to handle the weight
of the hood.
Note:
If the construction is not strong enough, do not proceed until rectified.
6. The term “top of the coil” refers to the top edge of the brackets and hood which house the curtain
(The curtain in the fully open position is referred to as the “coiled curtain”. The top of the coiled
curtain is not actually located at the “top of the coil”, it is lower than the top of the coil) Locate the
“top of the coil”:
a. This is typically at the top of the wall bracket.
b. If there is a ceiling at the top of the coil, skip the next step.
7. Mark a line at the top of the coil at both guides of the unit. Project the lines together to make a
continuous line.
