Arrived on site per customer request of getting a new venting system made up for a 1200 CFM Kitchen Range. Upon arriving we discussed the situation with Jennifer and made her aware of the necessary components involved with running such a big fan. CPI will be running a new venting system through the roof for the kitchen range. Todayâ€™s work involved us installing a new fresh air makeup with a damper that attaches to the return air duct. CPI will be installing the venting for the kitchen range once the appliance guys set the range as well as the blower on the roof. Jennifer will be calling to schedule us out once she finds out when the appliance guys will be coming. Note: CPI is not responsible for hooking up the electrical for the damper, an electrician will be needed to power up the transformer. Thank you for choosing CPI plumbing and heating Inc.
