Ventilation Installation
The Artisan X-e Base Model
roaster must be exhausted in accordance with the manufacturer’s instructions
as documented in the prior section of this manual. The roaster exhaust system must be independent of all
other systems.
Exhaust Penetrations
Any wall or ceiling penetration of ducts that transfer roaster exhaust must meet the International Building
Code fire-resistance rating and cannot be located within any fireblocking* and/or draftstopping* areas.
Unless, such duct work is constructed of galvanized steel or aluminum of a thickness specified in Section
603.3 of the International Building Code and the fire-resistance is rating is maintained.
*Fireblocking: Prevents movement of flame, smoke, gases through concealed spaces. Primarily
addresses vertical movement.
*Draftstopping: Prevents movement of smoke and gasses through concealed spaces. Primarily
addresses horizontal movement.
Cleanout
All ducting from the blower discharge to the outlet terminal must have a means for cleanout. Exhaust duct
cleaning is required for all coffee roasting installations. Inspect exhaust tubing frequently. Clean or replace
if excessive build up is present.
Maximum Run Length
Maximum 5” diameter exhaust run shall not exceed 50’ (feet) from the exhaust blower to the outlet
terminal.
For every 45° bend included in the exhaust duct path, 2 ½’ (feet) must be deducted from the
maximum of 50’ duct work. For 90° bend included in the
exhaust duct path, 5’ must be deducted from the
maximum of 50’ duct work.
Example: There are two (2) 45° bends included in the exhaust duct path. The total maximum run
length for a 5” exhaust duct is now 45’ (feet).
Blower Intake to Roaster Ducting
Flexible ducting is acceptable from the roaster/chaff canister to the plenum. Flex ducting must be all metal.
DO NOT USE plastic dryer ducting or aluminum flex duct with plastic liner.
Blower Discharge Ducting
USE ONLY RIGID ducting from the blower discharge to the outlet terminal.
Exhaust Gas Temperature
The exhaust gas temperature must not exceed 170° Fahrenheit (76.6° Celsius).
