Ventilation Problems; Installation Of Baking Chamber Bricks - Marshal MB42 Installation & Operating Manual

VENTING PROBLEMS
If the venting of any deck oven is either restricted or forced in any way the baking characteristics
of the oven will be adversely affected.
Examples of restricted venting include:
• use of tees and elbows
• long horizontal runs without the proper pitch of 1" per foot
Insufficient make-up air can cause heated air and combustibles to remain in the oven shortening
the life of the components.
INSTRUCTIONS FOR INSTALLING BRICKS
1. Start by installing the brick used for the baking deck. These bricks are 2" Thick and must
be installed ROUGH SIDE UP. Push bricks together to eliminate any space.
