Unable to configure oxidized as a service

I can run oxidized from the cli without a problem. I copy the oxidized.service to the /lib/systemd/system

I’m able to find where the oxidized is install. by running which oxidized

[[email protected] bin]# which oxidized
/usr/local/rvm/gems/ruby-2.3.8/bin/oxidized

I modify the variables on the oxidized.service put point to oxidized

[[email protected] bin]# cat /lib/systemd/system/oxidized.service
#For debian 8 put it in /lib/systemd/system/
#To set OXIDIZED_HOME instead of the default:

~${oxidized_user}/.config/oxidized in debian 8, then uncomment

#(and modify as required) the “Environment” variable below so
#systemd sets the correct environment. Tested only on Debian 8.8.
#YMMV otherwise.

#For RHEL / CentOS 7 put it in /etc/systemd/system/
#and call it with systemctl start oxidized.service

[Unit]
Description=Oxidized - Network Device Configuration Backup Tool
After=network-online.target multi-user.target
Wants=network-online.target

[Service]
ExecStart=/usr/local/rvm/gems/ruby-2.3.8/bin/oxidized
User=root
KillSignal=SIGKILL
Environment=“OXIDIZED_HOME=/root/.config/oxidized”
Restart=on-failure
RestartSec=300s

[Install]
WantedBy=multi-user.target

I can do systemctl start oxidized and I get no error, but when I do systemctl status oxidized i receive the following.

[[email protected] bin]# systemctl status oxidized

Not sure what am I missing. Any pointers would be appreciated.
