Fireplace Control Wiring - success i just finished wiring up my gas fireplace up to smartthings tonight my fireplace as a small on off switch on the side which is basically just a contact switch plete the connect and the fireplace goes on it would be easy enough to replace the switch with a z wave relay but one thing in this activity we were instructed to redesign the fireplace control circuit for a residential gas fireplace the fireplace had four thermal sensors that when ever a flame was present would output a logic of 1 these sensors were connected to the fireplace control circuit which outputs a 1 to the emergency cut off valve to keep the gas flowing a zero 0 will turn the gas off well i finally got the fireplace automated here s how i did it and what i learned initial setup low voltage switch on the wall turns the gas fireplace on and off this switch has solid core 18 gauge wire running to it from the control.
module beneath the fireplace fan blower turns on off via thermostat inside of fireplace what kind of wall switch is needed for a natural gas fireplace to ignite consistently ask question 8 2 knowing the fireplace doesn t use the house power we could use it even during an outage i figured the voltage was low enough for me to troubleshoot remote switch wiring for a gas log fire place 1 p div div class b algotextcarousel id ce carousel 570771241 3 div id slideexp2 2886bac class b slideexp data wire i slideexp init b select i f selected o f active o data control id slideexp2 2886ba data appns serp data k 5436 1 data stk div class b overlay div id slideexp2 2886bachevrons prevbtn class btn disabled prev rounded bld data dir div class bg span span div div class vcac div style height 32px margin top 16px div class cr div div div div div div div id slideexp2 2886bachevrons nextbtn class btn.
